Mmmm, thanks for that, though it's going to be difficult to get to some places inside the tube.
Would I sponge the stuff on? How would I get the chlorine out/off afterward?
Yes Vermin about 1K or a little more. The main mirror blank I think was $200 back then. It's 30mm plate glass. I made the main mirror mount, made the spider too so saved $ here also.
Unfortunately it's also in very run down condition lately, and so am I so I don't really have the energy to fix it. Mirror need a recoat and the bearings need cleaning.
Since I've been unwell I've been drifting to smaller and smaller scopes these days. I love my 6 inch F5 and F6 Newtonians. Very light and still good for astrophotography. A bit dim for the eyes though, especially after being spoilt by a 16"!!
