New design - Annular ring OAG???
It just dawned on me that the new reflective guide slit I developed for the spectroscope could be easily adapted to provide an annular reflective "ring" for an OAG application.
Think of it as a flip mirror in front of your camera with a clear aperture of say 25mm diameter( or whatever was "optimum" for the CCD chip - it could even be a rectangular aperture to better match the CCD....)
The outer area beyond the clear aperture, out to say, 35-40mm diameter would be a highly reflective "ring" - this would provide a very large guide field of view - any star image found in the annulus could be used for guiding...
Comment/ questions/ concerns???
