secondary mirror recoating

Posted By steve cassel

Ted,

That's it exactly... Multi-coated silvered optics.

If that's really silver, I suppose the tarnish may not be that big a problem. Like he said, not worth the trouble of recoating the mirror.

Did he say the silver would have to be removed before recoating with aluminum? I'm guessing that the silver could be filling any imperfections in the glass that could be problematic in recoating with aluminum.

Thanks for the response.
---------Steve.

What did I see transit the moon?

Balloon sounds like a pretty good guess.
I've seen birds cross while viewing... Do you think it might have been a large bird?? Eagles get quite large and fly pretty high.
