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.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
