I am NOT an imager, unfortunately being Autistic I never will be as I don't have the necessary patience, but I am connecting my DSLR to my scopes.
Therefore I have the most basic problem you will all have overcome.
72mm ED Skywatcher and 120mm Triplet ED Esprit.
Can not focus on infinity, assuming not enough inward travel.
See images
I have tried attaching the camera directly to the scope (72mm) NO luck, attaching the camera via 2" diags to the larger scope, NO luck, the only way is to use a reducer? screwed into the front of the camera nosepiece
So, is that it
Thanks
