Hello,
I came across this article from sky and telescope and thought it held some great promise. In principle it pulls the mirror from spherical to paraboloid, eliminating parabolisation from the mirror making progress. The thickness of the glass and the focal lengths works well for the telescope projects I have planned.
Has anyone seen or used a mirror/mirror cell based on this design?
Thanks
Steve
