I already have an old Orion eyepiece holder/adapter, and am eying a few used eyepieces for solar system objects (currently a University Optics 18mm orthoscopic and an Orion 10mm Ultrasopic.) Obviously I want eyepieces that will physically fit O.D. wise into my eyepiece adapter, of course. My question is are there any caveats or gotchas, etc. when considering eyepiece selection for well-focused projection to DSLR? Is eye relief a major issue or eyepiece length. or are there any eyepiece designs that don't like focusing to a DSLR imager, etc.? TIA for any help!
