Hi

I got this 8'' dobsonian I bought second hand like 10 years ago, and I notice it has a lot of chips on the primary mirror , like the coating has gone

Is there something that can be done? Will it cause a big reduction in the quality of the images? I had some very bad views the last time i use it

I have also problems with the finder scope attachment. The tube is deform where the , so it cannot be align to be centred properly, so i was starting to consider buying a new scope al together, maybe even upgrading to a 10 or 12 inches or a newtonian in a mount.

What do you think
