Description

A group for discussing the parameters involved in the designing, building, and use for CCD imaging of Newtonian telescopes [other than mirror making]. For equatorially mounted Newtonians both German and platform.

The photo to the right reflects the idea of innovative design concepts [but not necessarily this or any other specific design concept] applied to the building of Newtonians for imaging. Ten inch f/7.2 Newtonian for lunar imaging with 3x barlow -- scope, mirror and design by Tony Gondola.
