What adapter for 2" eyepiece projection?
Hello:
I'm wondering what brand name those are and what you call those adapters to make a 2" eyepiece do projection for your DSLR?
I think some clamp on to a lip on the front of 2" eyepieces. And some have a tube that fits around the eyepiece.
I'm not sure which one is best for me. So far I've got a Meade 56mm, 2" eyepiece, and a 31mm Erfle, 2". The Meade one has that groove, lip that can use the clamp type.
I'm not sure about where the focal plane is for all those eyepieces is either. I'm worried about buying equipment (adapters) that are only for certain eyepieces or visa versa.
Thank you for advice.
