## Questions & Answers

**Q: How do you mount this to the top of a celestron c6 ota?**
A: I don’t know how to mount it to a Celestron.  I have a large dovetail bar on the top of my Ritchey that I connect accessories to, like guide scopes.  My recommendation would be to not use a Celestron product unless it’s an eyepiece. 🤷🏻‍♂️

**Q: Will this guide scope work for a c8 ota at f6.3 (1250 mm fl) on an avx gem?**
A: Most Astrophotography with C8 will use 60mm guide scope that is a starting point for guiding C8 with 6.3 reducer.

**Q: Will the zwo asi120mm mini work ok with this scope?**
A: Yes

**Q: Would this scope be a good match with the skywatcher evostar 72ed focal length of 420mm?**
A: Yes
