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. See the chart below to determine if your camera is compatible with RASA 8.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003e\u003cspan style=\"box-sizing: inherit; font-weight: bolder;\"\u003eUnique Optical Design\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eRASA’s optical design is patented (US 2016\/0299331 A1). 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 390-800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eAll refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings.

Combined with the RASA 8, it is a state-of-the-art deep-sky astronomical imaging system.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eThe CGX is an incredibly sturdy equatorial mount which rigidly supports the RASA 8. The mount was designed more compactly, so the instrument load is held closer to the R.A. axis, thus reducing torque from the load. It was also designed using FEA (Finite Element Analysis) software, which helped to optimize the stout structure of the mount. As a result, the CGX can support more weight than other mounts with similar mass. With its 55 lb. load capacity, it can easily handle the RASA 8, which weighs only 17 lbs., along with a camera and any accessories. Expect a vibration-free setup, even in somewhat windy conditions. The RASA 8 connects directly to the CGX with its CGE dovetail mounting bar.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eThe heavy-duty adjustable height tripod has 2” diameter steel tripod legs with an extra-wide stance for improved stability. Graduated markings on the tripod legs make it easy to extend them to the same height and level the tripod.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eDesigned with imaging in mind, the CGX motor drive system builds upon learnings from previous generations of mounts. You can trust CGX to accurately track 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 connect to the worm gears with a belt-and-pulley system (instead of spur gears) to reduce gear backlash when the motor changes directions. The steel worm gears are supported by precision bearings and spring-loaded against a brass worm wheel, which also helps ensure a smoothly operating drive system with minimal backlash and no binding.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eAll mounts have some amount of “periodic tracking error” inherent in them caused by tiny gear imperfections. To mitigate this, the CGX 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 CGX 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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\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. CGX 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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eThe NexStar+ also has dozens of other functions to control every aspect of the mount’s behavior.

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 (see “Ready for Remote Imaging” section below). There are also 2 AUX ports on the mount that can support optional accessories such as StarSense AutoAlign.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eTransporting the entire system to a dark site is extremely manageable, even for one person. The optical tube, mount head, tripod, counterweight bar, and counterweight all disassemble into separate pieces. The only tool ever required is a supplied hex key, which has a holder built into the mount, so you can’t lose or forget it. CGX also features two ergonomic carry handles that make carrying and setting up this heavy-duty mount much more comfortable. When it’s time to transport your mount, the tripod accessory tray “nests” into the legs when collapsed, stabilizing the tripod in your vehicle and ensuring that you don’t lose the tray.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003e\u003cspan style=\"box-sizing: inherit; font-weight: bolder;\"\u003eReady for Remote Imaging\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eToday’s imagers do not necessarily want to be near their telescope outside when they are capturing images. Rather, they would prefer to be indoors controlling the mount and camera with a computer, while the telescope is in the backyard, or even hundreds of miles away in a dark remote observing site. Not every mount is capable of remote observing operation, but the CGX was designed specifically with this in mind. Celestron’s engineers thought through every scenario that might occur in the field, since it’s very likely that no one will be around to immediately “rescue” a remote telescope if something unexpected occurs.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eOne of the most critical problems that can occur during remote operation is the optical tube inadvertently striking the mount. This will not only ruin an exposure and require realignment with the sky, but could also damage expensive equipment. This type of strike cannot happen with CGX because optical switches on each axis stop the motors before the astrograph can run into the mount, without loss of alignment.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eShould power be somehow interrupted, the mount has “home position” optical switches that allow easy remote realignment of the mount. The mount’s cables are all wired internally through the mount, and all external inputs, including the power jack, are on a stationary section of the mount. This prevents cables from becoming snagged or tangled and unplugged as the astrograph is moving. The mount also has hard stops to physically limit the motion of the astrograph on each axis, preventing the internal cabling from being overly twisted or pulled and potentially failing. In addition, the hard stops provide a “fail safe” safety measure to protect the astrograph should the limit switches somehow fail. The power jack for the mount utilizes a threaded barrel connector, ensuring the power cable won’t become unplugged and cause the mount to lose power.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eFor remote imaging, the mount needs a way to be controlled by an external computer. The CGX has two ways to connect to a computer via USB 2.0. First, it has a USB port on the mount itself which is used exclusively to connect to a PC running the included Celestron PWI telescope control software. Developed in partnership with PlaneWave Instruments, the software has an intuitive graphical user interface and provides an excellent solution for remotely operating the mount. It incorporates multi-point mount modeling to provide the most accurate alignment of the mount to the sky possible. In addition, the included NexStar+ hand controller also has its own USB 2.0 port for computer connection; this can be used with optional third-party telescope control software by use of an ASCOM driver.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eIn summary, the CGX and RASA 8 together are a top-tier imaging system built for performance and ease of use.

In many cases, autoguiding will not be required.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eRASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eToday, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips.

At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A).
