Jerry,
           I used the Swarovski TLS - 800 eyepiece/adapter.

http://www.opticsplanet.net/swtls80035ca.html

This replaces the scope eyepiece and the camera lens so makes the 
whole setup more robust.  It doesn't give the magnification though as 
with the D3 it's only an 800 mm/f11 lens.  If you have a 1.5x crop in 
the camera then you would have a 1200 mm lens.
I have the old version which is not as good as the new model so I'll 
have to save up for it.  If anyone knows a cheaper deal on them let 
me know.
The setup would work better with a lighter DSLR , like the Canon 
400D, Pentax 10D or new Olympus E-420.
Neil.

I finally got my new support bracket from "my old photographer mate" 
in Sydney and with some adjustments ( Manfrotto sliding plate at the 
back ) I set out for the local park this morning in misty rain.
I was using the Swarovski TLS800 (old version ) to connect the camera 
to the scope.  Due to the low light levels the D3 was useful as I 
tested up to iso 25000 but was mostly shooting around iso 1600.
The whole setup was very firm.

Gorgeous photos, Roy. Either with the Pentax K10 or the Nikon 8400.
Beautiful, contrasty, saturated colors, and very sharp.

The threads should have had a surface treatment like anodizing to prevent 
this problem. You may want to return your system under warrantee. It is 
possible that you have abused the scope with dirt in the threads that has 
damaged the threads. You are the best judge. To answer your question I would 
recommend using  "Super Lube" on the threads. This is a synthetic based 
grease with PTFE (Teflon like additive). It does not migrate like 
silicone.DO NOT USE SILICONE!!!!!!!! For your application you would just 
slightly "wet" the threads. Put a little on the threads and wipe most of it 
off. Before you do this try to clear all of the dust out of the threads and 
the area. I have used this lube on a set of aluminum threads that were 
grinding themselves to pieces. It worked great, and only a slight "wetting" 
was required. The "Super Lube" is said to be non-toxic, but may cause eye 
and skin irritation. The website is super-lube.com. I am able to buy the 
lube locally. The manufacture has told me that it has been used in optical 
assemblies. Of course use at your own risk, but this is what I would do.

Maybe someone here can answer my question. I couldn't elicit a 
response from Zeiss directly. Here was my message to Zeiss:


Hello,

I have a question regarding my Zeiss Diascope 85T FL. Some time ago I 
purchased a Zeiss DSLR digiscoping adapter for my Canon DSLR camera. 
It works reasonably well. My question has to do with the thread on 
the scope body for screwing the adapter in place. I notice since the 
thread is very fine and it takes several turns to seat the adapter in 
place that there is a fine powder or dust that is emitted due to 
friction. I can see this as I screw the adapter on and off. Over time 
this dust accumulates on the inner glass surfaces- both on the 
adapter, and the exit pupil glass inside the scope. The thread 
appears very dry and no doubt contributes to the dust. Is there a 
particular type or approved lubricant that can be applied to the 
thread to prevent this dust from becoming airborne? I don't want to 
use something that is harmful to the glass surfaces by vapor or 
gassing over time. I appreciate your response.

Hello Russ:

	I have experience with a Leica APO Televid 77, 20-60x zoom  
eyepiece , Digital Adapter 2 and a Panasonic DMC-FX30k.

	The Leica C-Lux 2 and the Panasonic DMC-FX30 appear to be the same  
camera except for a small exterior design 'detail'.  Both have Leica  
optics,  and similar specs.  The FX-30 is less expensive.  $220 v.s.  
$499?  Included software is different for each camera.

	The FX-30 fits in the Digital Adapter 2.   The FX-30 does have a  
case design feature near the lens that causes it to raise up ~ 1/16"  
from fitting the adapter flush.  This can be easily adjusted so as to  
be not a concern.  This seems not to effect my photos. The extension  
of the camera lens upon turning the camera on,  is easily  
accommodated by the adapter.  The camera lens never touches the scope  
eyepiece.  Vignetting can be completely eliminated by using the zoom  
feature.   Please see attached photo of Trumpeter swans taken from  
~200'.

	Focusing is my biggest concern.  Keeping the LCD in shade while  
focusing seems to have the greatest positive effect on my photos.   
FX-30 does have boxes to tell you what are of the photo are in focus  
and three shot groups with one touch of the shutter release button.

	The FX-30 has a battery saving auto turn off feature that I haven't  
found a way to disable.  This feature can be defeated by a touch to  
the shutter release button. Just annoying when you're trying to  
focus, and keep the bird in the frame.  Every 10sec you have to touch  
the shutter release, whether you're ready to 'shot' or not.

This is dynamic and very interesting. The thought of being able to use a 6X

Subject: [digiscopingbirds] Canon A650 digital zoom test

As it's raining outside I thought I would explore the use of digital 
zoom in my Canon A650.  As a test I shot a series of images using 
optical zoom only, 1.5x digital zoom, 2x digital zoom and full 
digital zoom.
Here is a comparison image of the full optical zoom (6x or 210 mm ) 
and a full digital zoom (24x or 840 mm ).  The optical zoom (6x) was 
cropped to be the same size as the digital zoom image.  I ran Auto 
Levels and a mild Unsharp Mask over both images.
I will do some real life testing next week using different eyepieces on birds.
The reason for pursuing this line of questioning is the use of 
digital zoom to eliminate vignetting with a large range of eyepieces 
and the use of longer zoomed digicams for digiscoping.

Russ - 

The H3 has a big zoom.   'Nuff said.

What was the tube you used with the 4300 - the Nikon UR-E4, or something you 
made up? In theory you could do the same with either the Canon A590 IS, the 
Nikon P5100, or the Sony DSC-W130. 


Do yourself a money favor - Panasonic makes the Leica cameras and Leica makes 
the lenses for the Panasonic cameras. You can figure it out. 


The Sony N-series cameras are excellent, and personally I love the touch screen 
feature, but the adapter is problematic.

  Steve, Clay & Neil~

  Thank you for your suggestions. I have a Leica APO Televid 77 scope 
  with a 20x-60x zoom eyepiece. With my old Nikon coolpix 4300, I had 
  a short metal tube attachment that screwed into the camera and fit 
  somewhat snugly inside the rubber cup of the eyepiece. Nothing was 
  physically attached. The snugness of the metal tube prevented the 
  camera from moving off-center of the field of view. The optical zoom 
  of 3X eliminated vignetting. I would like something similar. 

  The bracket mounts sound like a hassle. The Leica (Digital Adapter 
  2) looks pretty good as one can attach it to the camera, have it in 
  the pocket/bag and bring it out when needed. The price is a bit much 
  as I need to replace the camera as well. I like the Leica C-Lux 2 as 
  one does not have to adjust the adapter once it is on the scope 
  because the zoomed lens doesn't touch the glass. However, it sounds 
  like this is for Leica "purists" as there are other cameras that have 
  similar features for 1/2 the price.

  A friend of mine recently came back from a Field Guides tour where 
  the guide was using a Sony Cyber-shot DSC-N1 with no adapter. I 
  haven't seen this camera, but would worry about touching the glass 
  with the camera lens.

  How is the Canon PowerShot S3 IS for digiscoping. It has 
  good "general" reviews.

Hi Russ,

The S3 IS is not a good camera for digiscoping because of the 12x
zoom. It will vignette very badly with most scope/eyepiece
combinations. It's best to stay with lower zoom (3x-4x) zoom digicams
for digiscoping.

Russ,
          You could use your tube solution on the Nikon P5100, 
although the thread could be different.
Have a look at the Canon A570/590IS .  The 12x zoom of the S3 IS is 
too much for digiscoping with a normal 20x plus scope eyepiece.
Neil.

    True. And in a *good* test, they would be. If scopes were tested 
like lenses are at places like www.photozon.de and www.photodo.com, we 
could lower the noise level from Cornell quite a bit.

Resolution charts are often used to test scopes and are often thought to 
provide a quantifiable measurement. They do, but one should not heavily 
weight this measurement. For scopes of  reasonably good quality the limiting 
resolution will be determined by the magnification and the aperture of the 
scope.  Two scopes can have the same score on the resolution test but one

Hi Scott - 

The prospect of China for 7 weeks sounds fun! I would add in the Canon A590 IS 
into the mix, along with the Canon LA-DC52G accessory adapter. The DCA will 
screw right on with the 52mm ring. 


The A590 IS is the successor to the A570 IS, which got a great review on DP 
Review http://www.dpreview.com/reviews/canona570is/ - far better than other 
similar cameras scored. However, to me the BIG plus of this camera is that it 
takes AA batteries - either alkaline, lithium, or rechargeable NiMh. The Nikon 
and Sony cameras both take proprietary rechargeable batteries, and if you do 
not take backups, or lose them, lose the recharger, or can't get access to a 
power source during the trip, you are screwed. You can find AA batteries in all 
corners of the globe. 


The A590 IS should be available everywhere - I just saw it at Best Buy here in 
the States for $179! Unbelievable - the A570 IS was $269 when it came out. 


Good Luck, and have a great trip,

  Hi all,

  My beloved Samsung Digimax V70 has finally frozen after over a year in
  the South American humidity. It's quite possible that I can get it
  repaired, but I am in a bit of a jam because I am leaving for a 7-week
  birding trip to China on Tuesday! So it appears I need to get a new
  camera ASAP. I'd pick up another V70 in a heartbeat, but only for the
  right price. (I'm currently bidding on one used on ebay.) I'm also not
  opposed to getting a different camera - the V70 did not last me very
  long in the super-humid conditions I regularly use it in and perhaps I
  could find something more robust. I will be in the US over this
  weekend so in theory anything sold there is in bounds. 

  After the photo marketing show in February, Clay mentioned that the
  Sony DSC-W120 works "fine" with an adapter, and I'm interested in
  knowing more about how well this camera digiscopes. Can anyone give
  more information? I would love to see some results if anyone has
  anything to show. The price and weight of this camera are attractive
  to me.

  It sounds like the Nikon Coolpix 5100 is a good option as well - can
  anyone give info and/or show results for this camera too? It sounds
  like a whole lot of (too many?) megapixels!

  Any other options I should be aware of?

  I'm shooting through a Swarovski ATS65HD with 20-60x zoom eyepiece and
  DCA.

  I have about a day to figure this out because I will probably need to
  buy the related camera-specific adapter online and get it shipped.
  Thanks for any help you can provide me in this dilemma.

Subject: Sony DSC-W120 vs. Nikon Coolpix 5100
From: "Scott Olmstead" <sparverius81 AT hotmail.com>
Date: Tue, 29 Apr 2008 14:04:59 -0000
Hi all,

My beloved Samsung Digimax V70 has finally frozen after over a year in
the South American humidity. It's quite possible that I can get it
repaired, but I am in a bit of a jam because I am leaving for a 7-week
birding trip to China on Tuesday! So it appears I need to get a new
camera ASAP. I'd pick up another V70 in a heartbeat, but only for the
right price. (I'm currently bidding on one used on ebay.) I'm also not
opposed to getting a different camera - the V70 did not last me very
long in the super-humid conditions I regularly use it in and perhaps I
could find something more robust. I will be in the US over this
weekend so in theory anything sold there is in bounds. 

After the photo marketing show in February, Clay mentioned that the
Sony DSC-W120 works "fine" with an adapter, and I'm interested in
knowing more about how well this camera digiscopes. Can anyone give
more information? I would love to see some results if anyone has
anything to show. The price and weight of this camera are attractive
to me.

It sounds like the Nikon Coolpix 5100 is a good option as well - can
anyone give info and/or show results for this camera too? It sounds
like a whole lot of (too many?) megapixels!

Any other options I should be aware of?

I'm shooting through a Swarovski ATS65HD with 20-60x zoom eyepiece and
DCA.

I have about a day to figure this out because I will probably need to
buy the related camera-specific adapter online and get it shipped.
Thanks for any help you can provide me in this dilemma.

Neil - 

I'm leaning toward making up an Adapter Sleeve like we have for the old-style 
zoom eyepiece. It will probably be shaped PVC tubing with a slit cut down the 
length so it will compress like the adapter sleeve does. That would give the 
DCA total contact across the entire barrel of the eyepiece. 


Now all I need is the time....

  Clay,
 Roy's got two extra screws tapped into his DCA collar which makes it much 
firmer. I'm going to do the same with mine. The 20x really needs it. 

  Neil.




 Hmmm....good point about the grip tape. Can it hold the camera firmly enough 
without allowing the DCA Base to wiggle? I might experiment with it next 
weekend in WA (my fixed eyepieces are right now on their way out there via 
UPS). 


 Yeah, herons and egrets are easy - too far away and heat shimmer will kill the 
image quality, so heron shots taken at +50 yd / m are usually for ID purposes 
only, so 1000mm works fine with them at < 100 ft. However, we both like to play 
with passerines in the woods, and having 1600 - 1800mm makes things more 
interesting and a lot more fun when photographing 6" long birds at 20 - 60 feet 
away.

      Clay,
 You don't need more than 1000 mm when photographing egrets/herons/ibis at 
places like Vierra.I shoot the 8400 on the 30x at 1100mm most of the time. It's 
nice to have more light too. I think I would use the 20x and the 45x with the 
D3. My support bracket should arrive this week so I will give it a go next 
weekend. 

 All you need for the DCA Zoom is some tennis racket grip and just wrap it 
around the eyepiece until the DCA collar will just slip over it. 

      Neil.




 No. Honestly, I don't want to have to mess with the DCA-Fixed to get it to 
work right. I am contemplating fabricating an Adapter Sleeve to allow the 
DCA-Zoom to work on a fixed eyepiece, but haven't made the time to do so. 




 Actually, if I were to try out using a fixed eyepiece with the Pentax, the 
30xSW would give me a final 36x, which might be more useful. The 20xSW would 
give 24x, which is the same as using the TLS 800. 




        Understanding the Math -

 Full Frame Sensor magnification: 50mm lens = 1x, thus 40mm Pentax = 0.8x 


 Pentax D-SLR body sensor = 1.5x crop factor when compared to Full-Frame Sensor 


        20x eyepiece = 1000mm 

        30x eyepiece = 1500mm



        Pentax body + TLS 800 = 1.5 x 800mm = 1200mm = 24x

        Pentax + 40mm lens + 20xSW = 1.5 x 0.8 x 20x = 24x

        Pentax + 40mm lens + 30xSW = 1.5 x 0.8 x 30x = 36x

Subject: A570 IS with Nikon Action 10x50 Binocular for Beginner?
From: "CJ" <cja2001 AT yahoo.com>
Date: Tue, 29 Apr 2008 02:43:15 -0000
As a bird lover and long-time amateur photographer, I'm interested in
getting started with what one member called hand-held and "minimalist"
digiscoping.

That's not only for cost reasons, but also because I'm looking for
something fun and easy… not professional.

The Canon A570 IS was recommended to that member, but the thread did
not go further to suggest what was next.

I was already considering the Canon A570 IS and I need a set of
binoculars, so, this is the direction I'm going:

I have the A570 IS ordered and am looking at the Nikon Action 10x50
Binoculars.

Is that a combination that can work?… and if so, what else do I need?

Thanks so much for your advice.

CJ

Hello New Member - 

Your DSC-H9 is a wonderful camera, but the 15x optical zoom makes it unsuitable 
for digiscoping. You can probably find an adapter that will attach it to a 
spotting scope, but the image will be severely vignetted, and the effort it 
takes to do that (both time and money) would be better spent in buying a second 
Sony like the DSC-W130 and Sony VAD-WE accessory adapter. That can be your 
"digiscoping camera", and the H9 can do all the other photographic jobs 


You can view the archives here for more information.

You did not specify the spotting scope you are planning on using - that choice 
will determine your options for adapters that can attach the camera to the 
scope, as well as the overall picture quality you can attain with the setup. 
How much can you budget for the scope and adapter purchase?

Hi Carl,

I tried to use a Televue 2x barlow with my Swarovski 80mm but the way 
the scope is weather sealed prevents being able to place the barlow 
forward enough. The infinity focus was reduced to about 22 feet.

The PF-CA35 is an eyepiece projection adapter. You can place a Pentax 
teleconverter (basically a barlow) between the PF-CA35 and the 
camera. I have tried this with my Swarovski eyepiece projection 
device and it works. This may cause some loss of image sharpness when 
compared with the PF-CA35 alone, and you may have better luck with a 
1.4x teleconverter than with a 2x teleconverter.

To me, it just underlines the fact that you should never go just on 
the basis of reviews, however respected the reviewer. If you are 
going to find the right scope, then there's no substitute for 
handling the goods and peering through the eyepiece before buying, 
and preferably in an environment where you can compare side by side 
with other candidate scopes. I'm lucky in having a nearby 
'scope/binocular dealer that is happy to let you compare whatever 
combinations he has to hand and take as much time as you need. 
Consequently, I have always come away from his establishment with 
something that actually fitted the need I had at the time.

Regards,
Tony

I tried using a eyepiece screw-in field flattener once, with my LOMO

through a pinhole (wasn't used thereafter). Bear in mind as well that 
the field flattener may reduce eye relief, depending on where it is

In 2005 at the Western Field Ornithologist Conference in Ashland 
Oregon, we did a massive scope comparison. Clay (or was it Roy, who 
worked for Swarovski then) put up a Swarovski resolution chart. We 
aimed all the scopes at the chart and cranked the zooms up to 60x. 
Scopes at the time included the Swarovski ATS/STS80 HD, the Kowa 
TSN-824 with the old eyepiece, Zeiss Diascope FL 85, Leica Televid 77 
APO, the Nikon Fieldscope 82 ED, the Pentax PF80 ED, and several others.

We did not collect data there either, only used our visual 
impressions. Our test consisted of seeing how far down the resolution 
chart each scope could go without the lines starting to merge. The 
Swarovski was the winner, with the Kowa and Zeiss close behind. Leica 
was next, and then there was a significant gap to the Nikon. Having 
used the Fieldscopes for about a month I had been impressed with its 
overall image quality in general use, so I was surprised at how far 
behind it was when viewing the resolution chart. Yes, I know that the 
zoom is 25-75x, and we tested both at 75x and 60x. The Fieldscope 
just didn't measure up to the others.

Russ,

It looks to me as if you are misstating your request and people are 
misinterpreting it. The way I read your request is that you want a 
camera with an adapter that does not replace the scope's eyepiece, 
and where you can attach the camera to the scope quickly. There are 
several ways to do this now, depending on what type of camera you want to use.

For dSLRs, your options are Kowa TSN-DA1 (for older scopes) or 
TSN-DA10 (for the new 770s and 880s) and Swarovski DCA. Each of these 
brands have an adapter where part stays on the scope but does not 
impede the use of the eyepiece (even for zooms), and the other part 
stays on the camera. To use these, you simply slide part B over part 
A, turn a thumb screw, and start shooting. This method also applies 
to point-and-shoot cameras that can accept filter threads.

For other point-and-shoot cameras, there are adapters from Alpen, 
Kowa, Leica, Nikon, Pentax, Swarovski, and Zeiss that allow most 
p'n's cameras to adapt. The Leica works like the filter thread style 
adapters above except it clamps around the camera, and some cameras 
are too large to fit. The Kowa TSN-DA4, Pentax UA-1, and Swarovski 
DCB (-A for angled scopes, -S for straight) adapters attach to the 
scope and let the camera swing out of the way when not in use. 
Finally, there are adapters from Alpen, Kowa, Nikon, and Zeiss (most 
of these are called universal adapters) that attach between the scope 
and the tripod. Of these, the Alpen and Zeiss swing the camera out of 
the way, while the Kowa and Nikon brackets require you to move a 
bunch of parts, and are not very fast.

The drawback of all the bracket style adapters, whether they swing 
away or not, is that whenever you have to change the battery or 
memory card in the camera, you have to realign the camera when you 
put it back on.

For the optimum in speed and alignment accuracy, go with the Kowa or 
Swarovski filter thread adapters or the Leica clamp-type adapter 
(Digital Adapter 2). Of course, these only fit the scopes of the 
respective manufacturers.

After reading the posted comments about Ken Rosenberg article I have to say 
that Cornell blew a great opportunity. Where is the data? Without the data 
there is no science. There were no consistent testing data just opinion. 
Consistency is so important. What was the control? Our old Digiscope polls were 
more scientific that this. Cornell should not have published this with their 
name attached, it hurts the credibility of a wonderful scientific organization. 
Properly done Mr Rosenberg almost could have published a masters thesis with 
the gear he had assembled. If the data was too much for a 4 page article just 
do one thing well. Shot gun approaches do not appeal to me, they lead to just 
opinions. Opinions are like anal sphincters, everyone has one. Just my 
thoughts.

After a little more research I would expect that Cornell had both the 45 degree 
prism and the 60 degree mirror diagonal at there location. Which one they used 
for which scope is not clear. 


I would like to thank everyone that commented on the review. It is always good 
to hear a variety of opinions.

  Clay here are a few comments:

 Thanks for pointing out that Swarovski uses Porro prisms. It looks like we 
both have made over statements about the type of prisms that are used in 
scoping scopes. A roof prism is being used in the Zeiss spotting scopes 
accounting to the website. Leica did use Porro prisms but in the soon to be 
released scopes are using a Schmidt (roof ) prism. Are you sure that Kowa uses 
Porro prisms? It is not clear from the cross section and is not stated from 
what I can see. The straight version does have an angle that looks like a 
Porro. I wonder if the 45degree could use a roof and the straight Porros. 
Pentax uses Porro prisms at least for the straight version. 


 A 45 degree roof prism does not require a mirrored surface, so total internal 
reflection still is the case for it. Some designs use a mirrored surface but 
that is only to make the path become straight like in binoculars. 


 I will check will Al of Televue this week about the type of diagonal sent, but 
since picture 14 on the Cornell website shows the 60 degree mirror diagonal on 
the Televue scope, I am fairly sure that the mirror diagonal was used. This 
diagonal does have a dielectric coating so has very little light lose. I agree 
with you that not having a correct left to right image is a disadvantage.

    Hello all - 

    A few quick points - 

 1) Cornell has reviewed the Pentax 80mm scope in previous years, but I don't 
have the older reviews handy to see if their methodology is comparable. 


 2) I think that there needs to be some clarification about spotting scope 
prisms vs. astro scope prism diagonals - 


 There is a decent article at 
http://sctscopes.net/SCT_Tips/Eyepieces/Diagonals/diagonals.html 


 All the major spotting scopes (Swarovski, Kowa, etc.) use porro prisms in 
their optical designs. Porros feature 100% light transmission due to total 
internal reflection off all reflecting surfaces. Therefore, there is no need 
for phase correction coatings, enhanced silver mirrors, or interference 
reflection (dielectric) coatings as are needed in roof prisms. Porros are 
larger, heavier, and do not fold the light as much as a roof prism does, but 
that is less of a problem with a spotting scope as it is in a binocular. 


 Astronomy telescopes in their basic form have no prisms whatsoever, and 
deliver an image that is both inverted (upside down) and reversed (writing is 
backwards). That's fine for stars and galaxies, not so good for following a 
flying gull. You then need a "diagonal" accessory to manipulate the image 
orientation. A 45-degree diagonal will give an image that is erect and correct. 
The Tele-Vue 60-degree diagonal gives an image that is erect but reversed, 
which is still annoying for birding (the Tele-Vue website includes a reference 
to a review by a pre-Zeiss Stephen Ingraham). Scott's comments about the 
diagonal choices are correct, but it remains to be seen which type the Cornell 
reviewers actually used. 


 Whether the diagonal uses a single reflective surface or a roof prism, there 
will always be the need for one reflection using a mirrored surface. A basic 
sliver mirror reflects somewhere around 90% of the light that hits it, while 
"enhanced silver" mirrors give about 95 to 96% reflectivity. William Optics is 
evidently claiming an enhanced mirror that achieves 97%. The diagonals that 
offer a "dielectric coating" will reflect 99% of the incident light - this is 
similar to what Swarovski first introduced in the EL binoculars as 
"Swarobright" coatings. 


 Also, the silver mirrors do not reflect the entire light spectrum with the 
same efficiency - the blue end of the spectrum suffers, while the dielectrics 
give very consistent performance across the spectrum.

 Though Chuck has some valid points, I was not turn-off as much as he was by 
the review. I would hope that others will read the article and decide its 
usefulness for themselves. 


 I too was disappointed that the Pentax 80ED scope was not reviewed. I have 
this scope so it would be nice to know how it compared to others. I think Chuck 
was surprised at the low rating of the Pentax 65mm. In other reviews this scope 
has scored high mark. I have test two of these Pentax 65 scope, both were 
rather soft. One was test side by side to a Leica APO scope of similar 
aperture. The Leica was noticable better; therefore I see the Cornell rating of 
the 65 to be about right. 


 One should also keep in mind that this and all other reviews I have seen are 
with respect to the visual performance of the scopes. When digiscoping the 
chromatic aberration of the scope is often more noticable, so scopes that 
perform about the same visually may produce different quality digiscoping 
images. 


 There is likely a mistake in the Cornell article with respect to the Televue 
diagonal. Cornell stated this was a 45 degree prism diagonal. I believe Televue 
would have provided a 60 degree mirrored diagonal. The performance with the 
standard Televue 45 degree diagonal would likely be poor because it is not 
phase coated and not color corrected. Figure 14 shows a Televue scope with a 60 
degree mirrored diagonal. The 60 degree diagonal produces nearly perfect image 
quality but presents an image that is flipped left-to-right. Most spotting 
scopes are now using phase coated roof prisms. These prism have improve greatly 
over the years, but still likely provide some image degrading compared to a 
single surface mirrored surface. The simpler diagonal is one likely reason for 
the slightly better image performance of the Televue 85 in the review.

          http://www.livingbird.org/NetCommunity/Page.aspx?pid=272
 Verrrry interesting, as Arte Johnson used to say. I find this review both 
mystifying and inadequate, in several ways. 


 First, about Questar, which I own. They talk about technology passing it by, 
but let's face it, there is very little technology to be passed by in a mirror 
lens. The effect of HD glass is minimal in a mirror design. Therefore, one of 
things they should have done is test it (and the others) with different 
eyepieces. That's where the technology would make a difference. In addition, 
the ratings for the Q are at 20x and 60x, like all the others. There is no 20x. 
That would require an eyepiece of 64mm. No way they had one (does one even 
exist?). Therefore I assume they meant 40x which would be the native 
magnification with a the Brandon 32mm eyepiece. (BTW, having tested the Brandon 
eyepiece against the Maxview 40, and having found that the Maxview is much 
better in photography, and that the opinion here is that the Maxview is an 
indifferent quality eyepiece, confirms my feeling that eyepiece trouble is the 
main factor.) Finally, the image quality at "20x" (40x) and 60x is, 
respectively, 4.5 and 4.3. I call Bull. Whatever the quality at normal mag, it 
goes waaay down when you use the flip-up 1.5X teleconverter. Basically, it 
sucks so bad I never use it. (Of course, they might have changed eyepieces 
instead of using the teleconverter, but I doubt it and they don't say.) 

 So, in conclusion, I would have to mistrust this report on any scope, based on 
what I know about one scope. 


 Secondly, it is mystifying that only one Pentax even made the list, and didn't 
do so well at that. Other reviews have been much more kind. Perhaps it is, 
again, the eyepiece used. One very important missing item in this test is a 
description of the eyepieces used. Another is that only zooms were used (which 
the authors admit, but still, it reduces the value of this test to limit the 
choice of eyepieces). 


 Thirdly, and most importantly, this is essentially a test of popularity, like 
a presidential election. There are no scientifically objective criteria at all. 
There are no resolution charts and there was no blind (let alone double-blind) 
testing. This I find absolutely incredible when a university puts its name 
behind it. Observer prejudice (hey, it's expensive so it must be better) is 
just one biasing factor that they did not eliminate. I also notice that the 
"Feel" category pretty much followed the overall ratings; the possibility 
exists that a 'harder-to-use' scope received lower image quality scores simply 
because it was harder to use. I have no objection to ergonomic ratings, but 
they must be separated from image quality, and without resolution charts, we 
just don't know if this separation was maintained. 


 Overall, the worst effect of this review seems to me to be eliminating some 
scopes from consideration by buyers. I know a careful buyer will check out the 
top scopes and make a personal decision, but the Pentax line in particular has 
been slighted by this review. I wonder who else has been declared a non-starter 
by this article.

    Sadly, no. A proper review would include objective criteria as well 
as opinion and interpretation. Automobile reviews include wheelbase 
numbers, tire sizes, acceleration measurements, etc., etc. Camera lens 
reviews include resolution figures. Washing machine reviews include 
water and energy consumption numbers. But this "review" is both narrow 
in scope [g] and 100% opinion, and because it is published under the 
banner of Cornell University it is going to be given an exalted status 
way beyond its modest accomplishments.
    Others have pointed out shortcomings even in the opinions. All of us 
could get better information by going on one birding trip and asking 
questions. The more I think about this review, the less I like it.

I had a similar concern about the way Nikon scopes (and, presumably the others) 
were 

handled.

It would appear that the ratings were based on a single combination of scope 
and eyepiece 

for each model tested. I use two eyepieces with my Fieldscope 82A ED and I do 
leave my 

glasses on. I almost always use a wide DS 30x eyepiece -- the eye relief is 
fine and the view 

is bright and clear. The 25-75x zoom is another matter -- it does not provide 
good eyerelief 

or nearly as bright an image. I'd criticize that eyepiece, not the scope.

Scott,

You're correct that it is an interesting review, though some members 
of 
this forum seem highly critical.  

When reading the review we do need to keep in mind that the rankings 
are based on the subjective opinions of the participants.  Each 
reader's interpretation of the results will then be based on their 
own 
subjective views towards each individual scope.  This is the same 
with 
any other product review.  It may stand out more with this review 
because we are dealing with products that are on the market and owned 
by many of us.  Thus, if you're happy with your Nikon Fieldscope, you 
may question why it ranked so low amongst the top of the line scopes 
(as an aside, I've noticed on another forum that there is a very 
loyal 
following amongst users of the Nikon Fieldscopes). 

Some of the forum members were also disappointed that certain scopes 
were not included in the survey.  Ken Rosenberg's article may provide 
an answer.  The article mentions that they survey "models sent to us 
by 
scope manufacturers."  The accompanying table also mentions that Wild 
Birds Unlimited at Sapsucker Woods also supplied some of the scopes.  
So, it's possible that the scopes that were reviewed was a product of 
manufacturer's choice (not also the reference to Leica in the 
article: "Leica was hesitant to send us their recently discontinued 
77mm APO scope, because they are introducing a completely redesigned 
line of scopes next spring that promises to be very exciting, but 
they were not yet available for testing.").  Maybe some of the 
members of this forum who are affiliated with one of the optics 
companies (or if there is a member of the forum affiliated with 
Living Bird) can provide greater insight.

My apologies for my first post on this forum to be so long.  It is 
an intersting review, and it does seem to provoke a reaction from a 
lot of people.  Given the variety of scopes in one place, I would 
have found it more interesting if they also ranked the scopes on 
digiscoping capabilities.  However, given that they were reviewing 
over 30 scopes, that was probably unrealistic.

Hi Russ - 

What type of scope do you have, with what eyepiece?   

As Neil said, depending on the camera's lens size and the inside diameter of 
the scope eyecup, you might have a few good choices available. There are quite 
a few Pentaxes and Olympuses (Olympi? Olympii?) that have favorable lenses for 
most zoom scope eyepieces, and each company has a waterproof model. The Canon 
Elphs (Elves?) are also usually scope-eyepiece-friendly, as are a couple of 
Sonys. In any case, your old CF cards will be useless for anything but poker 
chips, since all the current P&S cameras (except Sony) use SD cards. Not to 
worry, though, since a 1 gig SD card is selling for under $20 now. Amazing. 


I'll be at the Gray's Harbor Shorebird Festival in Hoquiem, WA this weekend 
doing digiscope demos. You could pop in and see what cameras / adapters work. 
Yeah, it's 387 miles from Coos Bay, but what the heck, it's only gas money...

the Pentax 65mm. In other reviews this scope has scored high mark. I 
have test two of these Pentax 65 scope, both were rather soft. One 
was test side by side to a Leica APO scope of similar aperture. The 
Leica was noticable better; therefore I see the Cornell rating of 
the 65 to be about right.

When digiscoping the chromatic aberration of the scope is often more 
noticable, so scopes that perform about the same  visually may 
produce different quality digiscoping images.

to the Televue diagonal. Cornell stated this was a 45 degree prism 
diagonal. I believe Televue would have provided a 60 degree mirrored 
diagonal. The performance with the standard Televue 45 degree 
diagonal would likely be poor because it is not phase coated and not 
color corrected. Figure 14 shows a Televue scope with a 60 degree 
mirrored diagonal. The 60 degree diagonal produces nearly perfect 
image quality but presents an image that is flipped left-to-right. 
Most spotting scopes are now using phase coated roof prisms. These 
prism have improve greatly over the years, but still likely provide 
some image degrading compared to a single surface mirrored surface. 
The simpler diagonal is one likely reason for the slightly better 
image performance of the Televue 85 in the review.

this review both mystifying and inadequate, in several ways.

>           First, about Questar, which I own. They talk about 
technology passing it by, but let's face it, there is very little 
technology to be passed by in a mirror lens. The effect of HD glass 
is minimal in a mirror design. Therefore, one of things they should 
have done is test it (and the others) with different eyepieces. 
That's where the technology would make a difference. In addition, 
the ratings for the Q are at 20x and 60x, like all the others. There 
is no 20x. That would require an eyepiece of 64mm. No way they had 
one (does one even exist?). Therefore I assume they meant 40x which 
would be the native magnification with a the Brandon 32mm eyepiece. 
(BTW, having tested the Brandon eyepiece against the Maxview 40, and 
having found that the Maxview is much better in photography, and 
that the opinion here is that the Maxview is an indifferent quality 
eyepiece, confirms my feeling that eyepiece trouble is the main 
factor.) Finally, the image quality at "20x" (40x) and 60x is, 
respectively, 4.5 and 4.3. I call Bull. Whatever the quality at 
normal mag, it goes waaay down when you use the flip-up 1.5X 
teleconverter. Basically, it sucks so bad I never use it. (Of 
course, they might have changed eyepieces instead of using the 
teleconverter, but I doubt it and they don't say.)

on any scope, based on what I know about one scope.
> 
>           Secondly, it is mystifying that only one Pentax even 
made the list, and didn't do so well at that. Other reviews have 
been much more kind. Perhaps it is, again, the eyepiece used. One 
very important missing item in this test is a description of the 
eyepieces used. Another is that only zooms were used (which the 
authors admit, but still, it reduces the value of this test to limit 
the choice of eyepieces).
> 
>           Thirdly, and most importantly, this is essentially a 
test of popularity, like a presidential election. There are no 
scientifically objective criteria at all. There are no resolution 
charts and there was no blind (let alone double-blind) testing. This 
I find absolutely incredible when a university puts its name behind 
it. Observer prejudice (hey, it's expensive so it must be better) is 
just one biasing factor that they did not eliminate. I also notice 
that the "Feel" category pretty much followed the overall ratings; 
the possibility exists that a 'harder-to-use' scope received lower 
image quality scores simply because it was harder to use. I have no 
objection to ergonomic ratings, but they must be separated from 
image quality, and without resolution charts, we just don't know if 
this separation was maintained.

be eliminating some scopes from consideration by buyers. I know a 
careful buyer will check out the top scopes and make a personal 
decision, but the Pentax line in particular has been slighted by 
this review. I wonder who else has been declared a non-starter by 
this article.

I wear glasses while 'scoping. And my TSN 883 works well with both my glasses 
and my Canon 870IS.
