Me, My Camera or Scope? (1 Viewer)

Hello all, just registered on this forum. I am new to digiscoping but wanted to augment my tools for photographing wildlife from a distance. I picked up a used Kowa 884 and purchased the adapters necessary for my Sony A7r. I have spent the last couple of days testing out the scope and having a heck of a time getting focus. I do have focus assist on the camera turned on. Have tried shutter speeds from 1/30 all the way up to 1/2000 and ISO of 100 all the way up to 20000!!! I just can't see anything really sharp at various settings from 20x all the way up to 60x (very tough getting enough light for anything above 35x or so). I use a video tripod and head that is probably overkill, but wanted to be sure not to blur by shake....also use remote trigger. Am I missing something? Am I expecting too much from the scope? Or could the scope be out of calibration? Or something else? Any suggestions very much appreciated. Jim

Hello again,

so maybe you could describe how you attached your camera to the scope - do you use a lens on the Sony body or is the body directly attached to the digiscoping adapter? In the latter case the scope will work as a fully manual objective lens - the focus drive of the scope is the only way to focus. With an objective lens the autofocus could theoretically work...

Also is the problem that you cannot reach focus at all or just have difficulties to get a good enough sharpness in the image?

If you get a sharp view through the eyepiece at 60x, the scope should at least be ok.

I think if you are using an eyepiece you definitely need it on the lowest magnification
