Hallo to all Bird-lovers,
i've finally decided to make a leap in bird-watching from my old beroflex 500 mm. I plugged it to my canon eos 5d mark II mainly for filming white herons' colony i've been watching during the last year. As the pics and videos came rather dim with this one (canon 24-105 is ok but the birds are rather far) i decided to buy something with wider aperture and also to get a decent telescope.
After reading a lot on the subject it appeared that sky-watcher ed80 ota pro (as it is sold in my country) was the best buy in the price range of $600-800. I checked it before byuing with the vendor and connected my canon to the scope with canon t-mount. The results dissapointed me - 10-15% of vignetting on the edges. Some sellers recommended to buy reducer/flattener for another some $250 but no chance to find both in one shop to check. Some say that it's inevitable and both pics and videos should be cropped. Or it's just the problem that full-frame camera does not fit to this one? Another seller recommended astro-tech 65 (sold for some $700 in Ukraine) but i doubt i get good results with such an aperture. As I see so many owners of ed80 sky-watcher/orion on your forum i want to ask for your advice. Will extention tube eliminate this? Do i really need flattener for birds? What about 2x teleconverter for canon system with this scope? I postponed the purchase so far, looking froward your advice.
