billyharris72 Posted April 27, 2017 Share Posted April 27, 2017 Like this. Nice little gadget if you have a decent telephoto or zoom lens to go with it. A lot less pricey than the telephoto / scope hybrid that Kowa does. Though in fairness, costing in a good telephoto lens the Kowa probably works out about a third of the price, so this might actually be a good option for someone wanting a quality telephoto lens who doesn't need AF. http://www.bestspottingscopereviews.com/KowaTelephotoLensScope-10.htm Link to comment Share on other sites More sharing options...
Ags Posted April 28, 2017 Author Share Posted April 28, 2017 Unfortunately the eyepiece is not changeable and the orientation is 45-degree spotting scope, not 90-degree astronomical. I am toying with the idea of combining one of these: http://www.teleskop-express.de/shop/product_info.php/info/p7835_TS-Optics-Optics-Adapter-for-Canon-EOS-Lenses-to-T2-for-CCD-cameras---with-1-4--photo-thread.html With a barlow to get extra backfocus and a diagonal and my 9mm speer waler... The neat thing about the above TS adapter is it has a photographic mounting thread. But I'm not sure there would be enough backfocus. Link to comment Share on other sites More sharing options...
Ags Posted May 5, 2017 Author Share Posted May 5, 2017 Still thinking about this. The eyepiece position is just wrong on the Kenko. Also its tripod foot is a bit flimsy according to reports. So I am thinking of building something. The focal point of a Canon camera lens is 55mm from the back of the lens. This adaptor takes 19mm of length and provides a metal photographic mounting foot and a T2 thread on the back: http://www.teleskop-express.de/shop/product_info.php/info/p7835_TS-Optics-Optics-Adapter-for-Canon-EOS-Lenses-to-T2-for-CCD-cameras---with-1-4--photo-thread.html This adaptor converts T2 to a 1.25 accessory tube: http://www.teleskop-express.de/shop/product_info.php/info/p7881_TS-Optics-Optics-Adapter-T2-to-1-25----adapts-eyepieces-to-male-T-threads.html This 2.6x path corrector for binoviewers would screw into the diagonal: http://www.teleskop-express.de/shop/product_info.php/info/p5806_TS-Optics-Optics-2-6x-Glass-Path-Corrector-for-binoviewers---full-compensation.html And I already have this cheapo diagonal: http://www.teleskop-express.de/shop/product_info.php/info/p290_1-25--Star-Diagonal-Mirror---90-.html I would have 36mm of optical path left after canon mounnt-T2 adaptor, so times 2.6 that gives 93mm for the diagonal etc, so i should be able to reach focus. If I have too much path I can just slide the path corrector back down the drawtube. If I still don't have enough backfocus I can remove the eyepiece holder from the diagonal and the eyepiece barrel from the eyepiece, and mount the eyepiece directly onto the diagonal. Combining with a 32mm plossl with a 2.6x path corrector (barlow surely?), that would yield 12mm Kenko-equivalent. Assuming EF-S lenses could mount on the canon-T2 adaptor, that would give a scope with 7-20x zoom. Link to comment Share on other sites More sharing options...
