In the RASA design, the imaging sensor lies at the front of the telescope tube, not the back, creating an ultra-fast f\/2.2 system with an extraordinarily wide field of view while providing sharp images to the edge. Since it launched in 2014, RASA technology has become the go-to choice for space surveillance and satellite tracking. National defense contractors, professional research astronomers, and governments trust RASA to detect tiny pieces of debris and space junk, keeping our vital communications satellites safe in orbit. For Origin, Celestron’s optical engineers developed a brand-new 6” RASA with all the same capabilities of an observatory-grade instrument in a grab-and-go package.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThanks to RASA, Origin Mark II is in a class of its own, far outperforming other telescope designs.
