Celestron Telescope RASA 8 f/2.0, OTA Only 91073

If you are in need of a fast f/2.0 equatorial system, then check out Celestron's RASA 8 telescope. With the fast f/2.0 optics, Celestrons RASA 8 Astrograph lets you capture detailed images of the night sky, even nebulae and galaxies. That means you can easily capture the rings of Saturn, the Veil of Orion, and even the Orion Nebula without the lengthy exposure times needed for longer telescopes. With the RASA 8, Celestron has created an equatorial mount that is compact enough for visual use and is easy to operate. They have also added an internal filter mount and a dovetail mounting bar to this OTA and made it compatible with the ion assisted CGE dovetail system. The Celestron RASA 8 is a powerful way to see the brightness of the stars and get a virtual real-time experience of them with your imaging devices.
