4. Next, with the mirror facing up, place the mirror cell assembly under

running, room temperature water for about (1) minute.

5. Turn the water off and pour a generous amount of the premixed

distilled water solution over the surface of the primary mirror.

6. Then take the cotton balls and saturate them with the premixed distilled

water solution and lightly swirl them on the surface of the mirror. You

don't have to swirl the mixture so as to create a lot of bubbles on the

surface, agitate it only enough to see a hint of the soap in the solution.

That will usually be sufficient to remove most stubborn dirt or stains on

the surface.

7. Next, with the mirror facing up, place the mirror cell assembly under

running, room temperature water for (1) minute, except after one

minute turn off the water and quickly flush the surface with a generous

amount of distilled water.

8. After the surface has been flushed with distilled water quickly turn the

mirror cell assembly on its side to drain off excess water. Then take the

bathroom tissue pad and lightly and gently blot the remaining water

from the surface.

9. Next, using a paper towel, carefully wipe up the water on the large and

small platters of the primary mirror cell. Avoid turning the assembly

upside down, and also, avoid touching the freshly cleaned mirror

surface. Inspect and repeat procedure if necessary. Reinstall mirror cell

assembly in tube assembly.

Because of the crucial nature of the secondary mirror alignment, it is advisable to

remove and/or clean it only if there is an excessive amount of contaminants on

the surface. To remove the secondary, loosen the hex nut/threaded rod

assembly that secures the mirror itself to the "L" shaped stalk. If you need

remove the secondary for cleaning be sure to measure the exact distance that

the second hex nut is threaded into the brass rod. That will mark the position

when the secondary is reinstalled. If possible, use cleaning methods that allow

the secondary mirror to remain in place. Try blowing the surface off with low

pressure air or wiping the surface with a soft camel hair brush and then gently

rake the surface with a bathroom tissue pad dampened with a small quantity of

alcohol or methanol. And as always, DGM Optics™ will be glad to give technical

support if needed.
