Question 3

This s137 svbony barlow hits the diagonal mirror on my mak telescope. what is the issue here? why is this happening?

Accepted Answer

thanks so much for your question.
If the eyepiece end of your diagonal mirror is too short, please put the Barlow mirror out a little, and tighten the screws a little when fixing it. If the gap between the Barlow mirror and the diagonal mirror is large, you can try to add a gasket.
