22 Inch Compact Scope Finished
Just finished my latest project - a scope based on the Greg Babcock/Obsession UC et. al. design with a 22" diameter, 1.7" thick F3.6 mirror. The ultimate compromise between aperture and usability!
6 interlocking 1&1/4" poles bolt directly to steel brackets connected to the sides of the mirror cell at the bottom and steel brackets bolted to the steel secondary spider at the top for maximum strength and rigidity.
Oversize bearings allow scope to balance and foldover for transport and storage. Continual strips of teflon and rounding over the tips of the arc on the rocker mean that the join in the bearings is not felt as any "bump". The bearings are reinforced with steel to make them nice and strong.
Accessories include Moonlite focuser, Secondary Dewguard, Telrad, Argo Navis and Servocat Junior for GOTO
The Servocat Junior may seem a little undersize but they have been fitted to 17.5 Discovery scopes - this scope is the same weight with better leverage due to a greater diameter ground board and Altitude bearings.
