New GSO Dob, crappy looking mirror.
G'day all,
So I went and bought a GSO 8" Dob today, took it home and put it all together. Upon looking at the primary I noticed it is not round, so I wondered if the coating was faulty. I shone a torch down the tube to get a better look and the mirror is very dusty to start with and I also noticed that it has streaks all over it , like some one has cleaned it with a wipe or something. Like streaks on a window after cleaning it. The coating doesn't look like it's failing but just has a straight edge 1/12th around the top of the mirror and only intrudes about the same as the primary retaining clips.
Is this normal for GSO Dobs?
