Focusing is easier, more accurate, and more stable than ever. The key to the Ultra-Stable Focus System is two sets of precision bearings that are precisely aligned and tested during assembly to ensure optimal results. With the launch of the 8 RASA, Celestron is unveiling a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. With the launch of the 8” RASA, Celestron is unveiling a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. The prime focus focal plane is located at the front of the optical system, so it cannot accommodate a traditional eyepiece. Purely designed for imaging, the 8” RASA cannot be used visually. The Celestron 8 ROWE-ACKERMANN (RASA) is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide. It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar. With the 8” RASA joining the lineup, a wider range of astroimagers can enjoy the benefits of the RASA design.
#CELESTRON RASA 8 PORTABLE#
The latest addition to the RASA family, this 8” version is a much more portable and affordable version of the heralded RASA 11, which was introduced to much acclaim in 2014.
It can capture stunning deep-sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost of those systems.
