45 deg. Erecting Image Diagonal Prism for Quantum 4

Posted By Michael Francis

I was wondering if anyone knows of a 45 degree Erecting Image Diagonal that would fit the axial port on my Quantum 4? Or anything like a camera adapter that would fit. Seems to be a different size than I am used to and definitely don’t want to mess up the threads. Looks like that arm on the bottom dial would hit most anything you tried to put in there. Thanks for looking.

Thanks, 
I guess what I’m looking for is a camera adapter for a Quantum 4. I wonder if there is any present day camera adapter that will work in a 1977 telescope?
