Making an Eyepiece Adapter
I have a 30mm 80deg UW 2" eyepiece and would like to experiment by attaching it to my QHY8 CCD, have the equipment to make the adapter but no sure what distance the CCD chip must be to the surface of the eyepiece - is there a formula. Maybe someone already tried if so is it worth the effort.
Much appreciate your help.
