Last week it was time to take the mirrors out and clean them. The primary was really dirty from about a years worth of use outside. I also decided to replace the primary mirror's center spot. The scope is an Orion 8" f/3.9.
I used a Rigel WiFiAline to get the secondary situated under the focuser. Then used a Farpoint 2" Laser and a Farpoint 2" Cheshire.
The weather here in north San Diego county has been terrible since I did this so I haven't had a chance to see if it is better or worse than before the cleaning. So any comments are welcome.
Thanks!
