You might need UV eye protection looking at Jupiter with that!

I wonder what the mirror is coated with :question:

Clements finished the telescope and in late September, he said he put a reflective coating on the mirror with a weed sprayer.

It's a silvering process. I'm headed over there tonight.

The GRS burned Permanently into your Retna!
I wonder what F ratio it is?
It looks like the drive is by hand winch... that is so cool. I wonder what that thing is worth.. besides Priceless!
WAY TO GO... Only in America... I'm pretty proud of him...
If he ever gets to Iowa he better look me up..
I wonder if he is a member here?

I'm guessing he sprayed either SILVEX or STERLING :lol:

Amazing! Did he ever test the mirror? You probably need to use a lighthouse as the light source for a Foucault test.

I bet he is silvering it with Tollens reagent and glucose. In the old Days you coated your mirror with pure silver chemically deposited on the glass. Google Tollens reagent.
I think the process is covered in the ATM making books.

youre basically using Silver nitrate as the source and manipulating it to precipitate pure silver on your mirror face. That's how they were initially going to coat the 200" mirror at Palomar until Vacuum Aluminizing was perfected by someone I forget his name now. Silver nitrate is not that cheap, especially since yould need to recoat it a lot more often than Aluminizing. It would be interesting if someone has found a similar process to spray on aluminum. Just my guess, we will see when you report back.

Mikes mirror may have been made for something like the KH series:
