Cleaning the primary mirror of an 8" Ritchey-Chretien telescope

As part of the process of exchanging the stock focuser with at more capable unit from Baader Planetarium, I will be taking the telescope apart and washing the primary mirror to remove the dirt accumulated on the surface during long nights under the starry sky. This video shows what tools to use, how to disassemble the scope, remove the secondary and primary mirrors, as well as how to wash the primary, before putting the whole thing back together again. The installation and alignment of the new focuser will be the subject of another video. Don't forget to 'like' the video, and maybe subscribe to my channel if you want to see more videos of this kind.
