Tips and tricks: an adaptor for straight scopes
by John Judge, Ken Bowles and Stéphane Moniotte
I have then put a 28mm-37mm step-up ring to the lens and then the lens cap that fits this I have cut a hole out of the centre and then it fits snugly inside the scope eyepiece with the plastic cap protecting the scope lens. I have also tried this set up on an angled scope and with a few minor adjustments (a steeper bend on each end) it would also work. I hope this might be of use to any other birders with straight scopes.
Another informative page has been written by Ken
Bowles, on his page dedicated to Scope
and Camera Arrangement. Ken describes his platform for mounting both
camera and scope (Leica APO Televid 77 scope in the straight-through configuration)
together with a very effective viewfinder.
