Re: 6" f9 Orion Ritchey-Chretien Astrograph
The bit I understand is that it is primarily for Astrophotography.
I do not do Astrophotography.
I am wondering if It can be efficiently used as a visual telescope.
Thank you for any insight you may be able to share with me.
Regards
Mark

Re: 6" f9 Orion Ritchey-Chretien Astrograph
Just about any Astrograph can be used as a visual scope if you can bring the eyepiece to focus. In this case with a diagonal and any of the normal range of eyepieces it does come to focus and can be used as a visual scope. I know this because I have done this. At least with my TPO.
