|Greg, from Pinellas Park, Florida, sent me these photos|
of his telescope and cleaning the primary mirror.
This telescope is an 8" F6 with ETT option.
|Removing the mirror is easy with a serrated|
cutting knife. Just "cut through the silicone"
using a "sawing motion".
|Just rinse the surface with water. I don't worry about using|
distilled water -- the water isn't on the surface long enough
to make any difference.
|Stand the mirror on edge to let the water drain. I use the corner of a paper|
towel to remove any drop that stay on the surface.
|In my telescopes, many of the mirrors are held in place with silicone.|
Don't forget some sort of "spacer" so the silicone will cure. I like
to use 1/4" "bumperons" -- but cardboard from a shoe-box works well.
Thanks for the photos Gary.

|Scott's 12" mirror is sufficient thickness that a non-flotation|
mirror cell is more than adequate Here, the 6-points have been
optimized with Plop
|Once the mirror cell is affixed to Scott's mirror, it'll be time,|
I'll finish the mirror board.
|Clamps, clamps clamps -- for Scott and Keith's 12" strut telescopes.|
