First some perameters:
I can deal with the focal length, but any scope to replace it would have to have either a similar or shorter focal length. Any replacement would have to offer excellent optics with a larger aperture.
I've seen a 7" Questar and think it's good, but for that same $10,000 US, I was wondering what anyone else has had experience with.
Intes Micro makes a nice 10" MAK they sell through Teton. While I was on their web-site I looked at some radical R-C astrographs from ATM. Again within or close to the projected $10 K and larger aperture.
No I don't have that much burning a hole in my pocket, but am curious if anyone has seen larger MAKs or at least Richey's with highly rated optics.
