and gas nebulae are located and shows them to you at the touch of a button

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

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

Red light bar can be switched on as an orientation aid in the dark

Celestron - 9.25" EdgeHD (Optical Tube) mount and gas nebulae are locatedThe 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
