Greeting all.
I want to build my own telescope but don't have the time to make my own mirror so I am looking for somewhere to buy one. So far I have found
www.handsonoptics.com and
www.gs-telescope.com. My question for the guru's is how do I know a good mirror from a bad one and are there any other suppliers?
I plan to make a 6" or 8" scope as I want it to be easily portable
Thanks
Brett
