Thanks to those who posted the URL for OPTICAST. I logged-on to their 
site to find they have two mirrors available "off the shelf" for the 
public, a 4" f/4 ($36.95) and a 6" f/4 ($57.95).

The mirror itself consists of a gypsum substrate upon which a layer of  
plastic is molded, then aluminized and overcoated. The company claims  
they are quarter-wave.

Have any of you explorer's played with one of these mirrors, and if so, 
how did it perform? The price is incredible, yet I remain skeptical.

Happy photon gathering...Mark
