X derivations

I started some tests using the X95 lens module http://www.birdforum.net/showthread.php?t=333057

Still didn't reached a combo with a definition as good as the original STX95 but the image quality is good already although not spectacular as the original...
The limitation is at high powers and a barlow helped a bit. The best combo for now is with the Ethos 17. The photo shows the combo with a focal reducer that works - will put tests at www.pt-ducks.com but you can compare AFOVS at http://www.pt-ducks.com/cr-telescope..._cr-telescopes ...

X binoviewer

Observing with 2 eyes is much better...

However at high magnifications de resolution still isn't also the ideal...

The focus range allows >3x zoom, in the photo with constant 60 AFOV!

Had some other ideas of using a binoviewer with the X95 but will take some time to get the material to test it...

X photo lens

Not my main goal but it's the best image quality combo I reached from all 3 derivations...
Information about the use of the PMW with it, will be placed at http://www.pt-ducks.com/cr-photography.htm

For now see the info at the astrotelescopes section.

This solution is lower cost than the original Swaro for photo and also lighter. Will confirm the image quality with field tests but will take some weeks...

Solved!...

Found a combo material that allows high magnification use of the X modules - have a look at http://www.pt-ducks.com/cr-telescope..._X_derivations

Will have to test it on field and do resolution tests but seem that I found a high power alternative to X95 use!...

Did a short field test with the photo combo and it works well - the enclosed photo is a crop of a photo taken at equivalent 986mm (plus 1.6x sensor crop). Will compare it with the TMB combo in terms of photo quality but it's much more practical...

X lens for photo

I never made a real test comparing the X95 lens module to my TMB92, side by side, to use as telelens, due lack of time...

These holidays I remembered to only take my X95 instead of also taking the TMB92, saving space and weight, so took the adapter to use the X95 lens as a telelens - still didn't decided on a digiscopy adapter since have to use it also with the Optolyth 100...

Well I regretted not taking the TMB since missed some potential good photos of interesting duck species... As mentioned at the updated http://www.pt-ducks.com/cr-photograp...ing_telescopes I wish that Swarosvki will develop an adapter with correcting lens for the X lens modules to work as telelenses. Like that would be possible to get a 560mm telelens with the X95, and a 952mm using the 1.7x extender. Even better would be if Swarovski would release a variable extender from 1 to >2x, that could be also used on the BTX...
The lack of resolution can be noticed at the attached photos - the Netta photo almost wasn't croped
