George is the man to talk to if you want to talk about mirrors
Mike,

That problem with astigmatism is very common with the GS scopes. It is caused by the "SECONDARY" mirror not the primary. I will give you a call tonight and tell you how to fix it. If your not comfortable pulling the secondary mirror out of the scope and pulling the secondary assembly apart I am happy to do it for you.
