What if, instead of using a spotting scope for digiscoping, you used a monocular? Admittedly, the zoom capabilities would be lessened; for instance, if you used a 10x25 monocular, you wouldn't get the same zoom capacity as if you used a typical zoom setting of between 20 and 30x (the lower end of a spotting scope's ability, as recommended by digiscoping god Mike McDowell). Still, it might be a viable (not to mention low-cost) alternative to the big spotting scopes.
Oh wait... what about mounting to a tripod? Perhaps there is something that could be done to join the monocular--or WAIT! the camera!--to the tripod! Of course!
I love thinking out loud on my bloggy because everyone offers great advice! So please feel free to offer some advice.
The monoculars I'm considering. Note the large eyepiece lens on the cheaper one--critical for alignment of camera lens for digiscoping.
The digiscoping adapter I'm considering.
What do you think?
