This may be a silly question to be asking,
I wear glasses full time but when I use my telescope I remove them and focuses the scope without my glasses on and use the scope this way. The question I am asking is when I put my camera onto the scope do I first focuses the scope with my glasses on or can I do it with them off ,and if I do it with them off will it make any difference to the focuses of the camera
