  • Celestron 36cm (14″) Rowe-Ackermann Schmidt Astrograph (RASA) f/2.2 Optical Tube Assembly (OTA Only)

    $13,999.00

    This larger version of the original Celestron 11″ RASA was developed for the field of Space Situational Awareness (SSA). SSA is a project dedicated to detecting and mapping space junk in orbit.

    In 2015, SSA professionals discovered the smaller 11″ RASA is an ideal instrument for this application. With its fast focal ratio and wide field of view it can detect even small pieces of space junk traveling at extraordinarily high speeds. There are now dozens of RASA telescopes in use around the world every night scanning the skies to protect satellites, at a fraction of the cost of other systems!

    Celestron’s team collaborated with SSA experts to develop an even better telescope to meet this important need. The result is the 14″ RASA 36 which can detect individual pieces of debris measuring less than 1 meter!
