The telescope does not work with standard DSLR cameras. It is optimized for sensors with up to a 22mm diagonal, but performs well with sensors up to 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced. Additionally, we do not recommend pairing RASA 8 with any camera body more than 4” in diameter.

The design consists of a Schmidt corrector, primary mirror, lens group, and optical window. The lens group contains 4 elements and utilizes rare-earth elements. Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 400-800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image.\u003c\/p\u003e\n\u003cp\u003eWith many imaging systems, adding an extra piece of flat glass such as a filter does not change optical performance. However, that is not the case with super-fast optical systems like the RASA. Our engineers addressed this by designing the RASA with a removeable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window. Celestron offers a Light Pollution Imaging Filter designed specifically for the 8” RASA, which mounts in place of the optical window.\u003c\/p\u003e\n\u003cp\u003eAll refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings. This maintains high light transmission through the entire optical system.\u003c\/p\u003e\n\u003cp\u003eWhen compared with “Hyperstar SCT” systems, the RASA 8 provides better optical performance and field illumination.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCGEM II: An Excellent Platform for RASA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCGEM II is a sturdy equatorial mount capable of rigidly supporting the 8” RASA. Its 40 lb load capacity can handle the 17 lb optical tube with ease, leaving lots of capacity to spare for your camera and any accessories. The heavy-duty adjustable height tripod has 2” diameter steel tripod legs with graduated markings that make it easy to extend the legs to the same height. The 8” RASA connects directly to the CGEM II with its CGE dovetail mounting bar.\u003c\/p\u003e\n\u003cp\u003eThe mount is packed with functionality and conveniences that make imaging with the 8” RASA easy. The fully computerized mount will automatically “GoTo” any of the 40,000+ astronomical objects selected from the NexStar+ hand controller’s database and automatically track the object as it appears to move across the night sky.\u003c\/p\u003e\n\u003cp\u003eDesigned with imaging in mind, the CGEM II motor drive system accurately tracks during an exposure. At the heart of the system are low cog DC servo motors with integrated optical encoders. The low cog design helps the motors run smoothly, while the integrated optical encoders provide accuracy. The motors turn steel worm gears, which are supported by precision bearings, against brass worm wheels. These components also help to make the motor drive system operate smoothly and accurately.\u003c\/p\u003e\n\u003cp\u003eTo track objects in the night sky, the mount must first be polar-aligned. Celestron makes this process easier than ever with the innovative All-Star Polar Alignment procedure. No extra equipment, such as a polar finder scope, is required. (An optional polar alignment finder scope is available if desired.) Best of all, the alignment can usually be completed in about 15 minutes, even without a clear view of Polaris.\u003c\/p\u003e\n\u003cp\u003eAll mounts have some amount of “periodic tracking error” inherent in them caused by tiny gear imperfections. To mitigate this, the CGEM II has Permanent Periodic Error Correction (PPEC). This allows you to run a routine to record the periodic errors only once; the recording is kept in memory, and subsequently corrects for the mount’s periodic tracking error. If an even higher level of tracking accuracy is desired, the CGEM II also has a dedicated autoguider port to connect an autoguiding camera directly to the mount to correct for any residual tracking errors.\u003c\/p\u003e\n\u003cp\u003eConditions for imaging are best when celestial objects are at their highest point in the sky with the darkest background, called the meridian. But some German equatorial mounts have trouble tracking near the meridian because they need to perform a “meridian flip,” readjusting their position to avoid the tube striking the mount. CGEM II does not suffer from this problem, imaging through the meridian with ease and not requiring a meridian flip until the object is a full 20° past the meridian.\u003c\/p\u003e\n\u003cp\u003eThe NexStar+ also has dozens of other functions to control every aspect of the mount’s behavior. These include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMultiple ways to align the mount to the night sky\u003c\/li\u003e\n\u003cli\u003eAdjustable slew rates up to 5°\/second\u003c\/li\u003e\n\u003cli\u003eNorthern or Southern hemisphere compatibility\u003c\/li\u003e\n\u003cli\u003eAdjustable autoguiding rates\u003c\/li\u003e\n\u003cli\u003eHibernate mode so the mount can be powered down without loss of alignment\u003c\/li\u003e\n\u003cli\u003eContinual firmware development, with new features added regularly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn addition to the autoguider port, the CGEM II also has other ports to enhance and expand the capabilities of the mount. The hand controller has a USB 2.0 port for those who wish to control the mount with an external computer and optional third-party software. There is an AUX port on the mount that can support optional accessories such as StarSense AutoAlign.\u003c\/p\u003e\n\u003cp\u003eWhen imaging, cable management can be a problem. The camera has a cable, the mount’s power source has a cable, and additional cables can come from a computer connection and augtoguider. To minimize cable management issues and prevent unwanted snags, all cabling for the mount is housed internally. This also eliminates the need to connect or disconnect an external Dec. motor cable when the mount is set up or broken down.\u003c\/p\u003e\n\u003cp\u003eTransporting the entire system to a dark site is not a problem either.
