The Celestron RASA 8" Rowe-Ackermann Schmidt Astrograph is one of the fastest telescopes available, featuring an incredibly fast f/2.0 optical system perfect for high-speed astrophotography with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. This imaging telescope delivers a flat field without optical aberrations for razor sharp stars across a wide field of view and 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. The Ultra-Stable Focus System with precision linear ball bearing virtually eliminates image shift, while an integrated 12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust. Weighing in at just 17 pounds, it's easy to transport your 8" RASA to the most remote dark sky locations.
