Hi Matt. I'll throw my two cents worth in here. The mirror is no good Period. For a company of this type to release a mirror like this is inexcusable. Yes there are tolerances but not to this extent. Most beginners can make their own mirror much better than that. We tested some GS scopes at a star party last Christmas and a few at my local instrument making club and the GS ones were all correct. Nothing like this one. It would take a "while" to correct this mirror by hand. Glad to see they took it back.
Regards Cristian
