Saw this on the local news last night. I don't know if Mike is a member here. http://www.ksl.com/?sid=22987812&nid=148&title=steel-beams-and-a-giant-mirror-how-a-utahn-is-creating-a-galactic-first&s_cid=featured-2

Probably ~ 9m focal length, so the lowest useful power is ~ 150X with a FOV of not quite as large as the full moon. Perfect though for the tiny faint fuzzies and planetary nebulae.

Quote from the article:

Although the mirror has been ground and polished, it still needs its reflective coating. Clements, with Dodds' help, plans to do this with a special metallic liquid and an automotive spray gun.

What?? Has anyone heard of spray-painting a mirror?
