Re: Interested in Ottawa-based mirror coating for telescope optics?
I saw a Youtube video of the Moonward folks coating a mirror. Very cool. What kind of mirrors are you making, Rick?

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. Normand Fullum does have a good reputation and he does lots of other very cool things.. OK,

Re: Interested in Ottawa-based mirror coating for telescope optics?

Re: Interested in Ottawa-based mirror coating for telescope optics?

Re: Interested in Ottawa-based mirror coating for telescope optics?
I don¡¯t have any mirrors at all. Might there be a new customer promotion: ¡°Free mirror with every recoating¡±?

Re: Interested in Ottawa-based mirror coating for telescope optics?
Being able to drive to a coater always beats having to ship a mirror. But i, for i one, happen to not need any mirrors coated at the moment.

Interested in Ottawa-based mirror coating for telescope optics?
Hi Everyone, I've been toying with the idea of coating my own telescope mirrors. By coating, I mean vacuum physical vapor deposition with aluminum and some kind of SiOx overcoat. I might be able to

Hello all! I was fortunate enough to view a major, un-predicted outburst of Perseids (ZHR of 210 +/- 20) on the morning of August 14th from a dark sky site west of Ottawa. It was a spectacular, very

Re: hazy but clear enough for perseids
We are at Otter Lake, QC this week. Last night I had the 2 youngest and my wife on the dock to watch the "falling stars". The 6 six old I think pretended to see some meteors but I didn't believe
