How To Grind A Telescope Mirror? (Solved)

What is the most efficient method of grinding mirrors?

  • Roughness in stroke numbers, tool rotation, and disc rotation are all important factors in good mirror grinding. Making a tile tool out of tiles that have been broken with a hammer can help to increase the unpredictability of the game:) Always work with water on your hands! Prior to beginning to grind, sprinkle some water on the grit.

How long does it take to grind a telescope mirror?

It is really difficult to clean it without causing damage. Every few years, all telescopes are required to have their mirrors recoated. The mirrors of most telescopes are coated with a very thin coating of aluminum to protect them from damage. The Gemini Telescopes, on the other hand, have lately had their mirrors coated with silver, making them an exception.

Do telescope mirrors use silver?

According to Phillips, despite the fact that silver has greater reflecting characteristics, the majority of astronomical telescope mirrors have aluminum as their reflective coating. “You need barrier layers on top that can prevent anything from getting through to the silver without interfering with the optical qualities of the mirror,” says the scientist.

How do I keep my telescope from fogging up?

An aluminized Mylar space blanket or central heating radiator foil are also excellent choices for this project. The dew heater band can also be wrapped around the end of your finder, or around the end of your telescope, or around a little distance back from the objective lens or corrector plate of your telescope.

Can you clean a telescope mirror with alcohol?
