Re: Interested in Ottawa-based mirror coating for telescope optics?
Well, I'm not doing much right at the moment. Some time ago I finished a 6" f/4 (as yet uncoated) that I plan to use for a guidescope (prime focus - no secondary) for the Boltwood 16". And I have a

Re: Interested in Ottawa-based mirror coating for telescope optics?
I saw a Youtube video of the Moonward folks coating a mirror. Very cool.

Re: Interested in Ottawa-based mirror coating for telescope optics?
Again, Moonward may not be in operation any more. I notice their website is copyright 2003.

Re: Interested in Ottawa-based mirror coating for telescope optics?
I did not know about Moonward Coatings. I recently had a small mirror recoated by Normand Fullum. It seems like he did a good job and he has a good reputation from what I could gather.

Re: Interested in Ottawa-based mirror coating for telescope optics?
I grind occasional mirrors and I know at least one other grinder who might be interested. But we'd want to see some good results before sacrificing a mirror! ;) Not many people grind their own any

Interested in Ottawa-based mirror coating for telescope optics?

I might be able to
