| RE: Cleaning Telescope Mirrors

First of all you`ll need to remove the mirror from the scope. It may or may not be attached to a cell. If the mirror can be removed from the cell, then do so, or maybe you can clean the mirror while still on the cell. Either way the mirror must be accessible. Once the mirror is out, just take a cotton ball with luke warm water and gently drag the cotton ball over the mirror, do not use pressure. Use regular soap and water; using dish soap is good. Give it a couple dozen swirls with a cotton ball until the entire surface has been washed. Rinse with distilled water or store bought bottled water until all the soap is gone. You can let it air dry or use a squeeze bulb and blow the water off. If there are no water spots, then you are done. If there are spots, then you can use a window cleaner and gently brush and wipe with a cotton ball. Do not use paper towels, they can scratch the mirror surface. Do not use Rainex anti-fog or window cleaner, because the film it leaves can abstract the light from the mirror. Once you are satisfied with the clean mirror, re-install it and re-collimate. Good Luck!! |
