"Ruggedized" RCOS 24 inch f/8 Carbon Tube Telescope.
Maui Space Surveillance Site - RCOS .6m and the AEOS 3.6m.
This RCOS 24 inch f/8 Carbon Tube Telescope was delivered to the Maui Space Surveillance Site (MSSS) on Maui in May 2008 and installed onto the AEOS 3.6m as a finder / guide scope. The AEOS 3.6m is an f/200 and has an extremely narrow field of view.
The AEOS 3.6m is considered to be the World's premier satellite tracker. This 120 ton telescope slews at speeds approaching 20 degrees per second, so a "Ruggedized" design was preferred.
