Cleaning the Mirrors of a Newtonian Telescope

Cleaning the mirrors of a Newtonian telescope is a very dirty and very polarising subject! People are divided into two camps – those who will never clean their mirrors and those who aren’t afraid to do it often, if required.

The first group of people will probably tell you that it’s better to have 3 inches of dust on your mirror than to risk cleaning it. They’ll probably tell you a bit of dust won’t affect the viewing at all. They’ll tell you that they’ve only cleaned their mirror 3 times in the last 40 years!

The fact that i’m writing this article puts me into the second group, and the fact that you’re reading it, probably means you’re thinking about cleaning your mirror and want to know a) Will it damage my mirror, b) What are the risks, c) What’s the best way to do it.
