Anyone imported a Secondary from China for a 10 inch newtonian. My old mirror has lost its coating, and I need to replace, or re-silver it.
Am thinking as it is flat, a surface mirror film, or new mirror from China.
Just purchased a Second hand 10 inch mirror on Gumtree for $40. It is much better than my old one, so no longer thinking about re-silvering it with Silver, "Tollen's test for aldehyd."
My 10 inch mirror was in very poor condition. Covered with dust when I purchased that telescope very cheap, so did not know how bad the Aluminium surface was.
Also thinking about a mylar mirror film onto the old secondary.
