This incredibly fast f\/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely. Weighing in at just 17 pounds, it’s easy to transport your 8” RASA to the most remote dark sky locations.\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"product-summary rte\"\u003e\n\u003cp\u003e\u003cstrong\u003eRASA Performance Made for Everyone\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 8” RASA is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide field of view.

View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye.\u003c\/p\u003e\n\u003cp\u003eBecause shorter exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The 8” RASA’s relatively short 400mm focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required. Weighing only 17 lb, this optical tube pairs perfectly with a wide variety of mounts.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt for Today’s Latest Cameras\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind.
