Hi I have an 8" Celestron Schmidt Cassegrain, and I have a 13mm Plossl, a 40mm Plossl, and a 2X Barlow. The eyepieces are both made by Celestron.
When I am doing astrophotography I can only take pictures through the 40mm eyepiece because the opening in the 13mm is too narrow.
Is there another type of eyepiece where a 13mm would have a larger hole to look/shoot through? And if so what would be a good choice? Thanks.
I don't know that much about the different brands but I would like the quality to at least equal what I have now.
