Celestron - 9.25" EdgeHD (Optical Tube) mount 5" gear drive with reinforced

5" gear drive with reinforced ball bearings and gear drive rail for adjustment of the pull-out tube

Celestron engineers have solved this problem by incorporating an optical window into the RASA that can be removed and replaced with a filter

as well as galaxies and nebulae from the NGC catalog and planets

This is a mount assembly kit only and must be used with an approved 'Solar Film' such as the Baader Solar Safety Film here

ASI294MC Pro has the same mechanics as ASI1600 Pro

Celestron - 9.25" EdgeHD (Optical Tube) mount 5" gear drive with reinforcedThe EdgeHD optics (Edge High Definition) combine the compact design of a Schmidt Cassegrain with significantly improved imaging at the edge of the image. This optical system not only offers the properties of astrographs, but also produces completely undistorted, sharp images right up to the edge of the large visual and photographic field of view. Not only is the coma outside the optical axis corrected as with other "coma free" optical designs
