Stargazing Is it possible to clean a telescope mirror?

AI Thread Summary
Cleaning a telescope mirror after years of dust accumulation is a concern for many amateur astronomers. It is generally recommended to send the mirror out for professional recoating, especially if it has been unused for a long time, as the coating may require expert attention. Optic Wave Labs is mentioned as a potential service provider, offering reasonable prices for recoating. However, there are mixed reviews about their reliability, with some users cautioning against using their services due to past negative experiences. Ultimately, seeking professional help is advisable for optimal results.

not to hijack - but seems not worth a separate thread.

Is it possible to clean a telescope mirror?

About 30 years ago i bought Dad a 6" Meade mirror out of Sky&Telescope magazine.
We built a simple Newtonian with a redwood twelve sided tube. Local astronomy club deemed it "handsome" which Dad enjoyed tremendously.

It has now sat for fifteen years since his death and is quite dusty.

Is this something an amateur can do, or should i mail it someplace?

Suggestions welcome -

You will be better off sending the mirror out and getting it recoated. After sitting around that long the coating will almost certainly need professional help. Optic wave labs, for example, [http://www.opticwavelabs.com/coating.php] will strip and recoat a 6 inch primary for around $50, and the secondary for $30 [perhaps less]. That is not a bad deal.

Personally, I won't do business with Cary at Optic Wave Labs. Too risky. He hasn't taken any of my money but he has wasted a lot of my time. Search Cloudy Nights for the many tales of woe... and just as many happy endings. If you've already jumped in then good luck!

I think you'll need it.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
