But we're well aware of the challenges our favorite hobby can sometimes involve: trekking long distances to dark skies, precisely aligning and guiding an equatorial mount, and capturing hours of very long exposures to gather enough photons to see the spiral arms and faint details of our favorite celestial objects. In a quest to solve all those challenges, our engineers joined forces with storied optical designers Dave Rowe and Mark Ackermann to create RASA.\u003c\/p\u003e \u003cp\u003eWhile a traditional SCT telescope places the imaging sensor at the Cassegrain focus at the rear of the telescope, RASA places the sensor at the prime focus at the front of the telescope. Instead of imaging at f\/10 like you do with an 8\" Schmidt-Cassegrain (SCT), RASA works at lightning speed, f\/2—25 times faster! In 10 minutes with RASA, your image is as bright as it would be in 4+ hours with an SCT (albeit with a wider field of view).\u003c\/p\u003e \u003cp\u003eWhen you image with a RASA 8, you can use much shorter exposure times. Add a sensitive camera and the proper \"live stacking\" software, and the 8\" RASA can provide an almost real-time \"observing\" experience—even from the city. View images on a computer in seconds that are brighter and more detailed than you'd see through a much bigger telescope with the naked eye. Or capture and stack lots of short exposures and process the data; you'll be stunned at the details you can bring out.\u003c\/p\u003e \u003cp\u003eWhat's more, RASA's speed lessens the tracking demands on your mount. You’ll be using shorter sub-exposures so you won't need to track accurately over extended periods. In many cases, you won't even need to use an autoguider. And since RASA 8 weighs just 17 lb, it pairs perfectly with a wide variety of mounts, including the grab-and-go Advanced VX.\u003c\/p\u003e \u003cp\u003eAlthough RASA has revolutionized the world of astroimaging, its influence goes far beyond astroimaging. Researchers and government agencies around the world have discovered that RASA is the ideal tool for detecting errant space junk and asteroids. Arrays of RASAs are deployed worldwide, scanning the skies and protecting our satellites in orbit.\u003c\/p\u003e  \u003ch2\u003e\u003cstrong\u003eFlat-field Performance Perfectly Paired with Today's Cameras\u003c\/strong\u003e\u003c\/h2\u003e \u003cp\u003eThe 8\" RASA delivers a flat field without optical aberrations for razor-sharp stars across a wide field of view. It can capture detailed deep-sky astronomical images at a fraction of the cost of other slower and smaller telescope designs, like refractors.\u003c\/p\u003e \u003cp\u003eThe RASA 8\" 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. Purely designed for imaging, the 8\" RASA cannot be used visually. The focal plane is located at the front of the optical system, so it cannot accommodate a traditional eyepiece.\u003c\/p\u003e \u003cp\u003eUnlike the 11\" and 14\" RASA, which both work with DSLR and large astronomical cameras, we designed the 8\" model with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. (RASA 8 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 a 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. Note that 42mm full-frame sensors can also work, but performance diminishes at the edges of the sensor, and field illumination is reduced. We don't 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  \u003ch2\u003e\u003cstrong\u003eUltra-Stable Focus System\u003c\/strong\u003e\u003c\/h2\u003e \u003cp\u003eWith the launch of the 8\" RASA, Celestron unveiled a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. Precise focusing is easier and more stable than ever. The key to the Ultra-Stable Focus System is a precision linear ball bearing, which we individually test during assembly to ensure optimal results.\u003c\/p\u003e  \u003ch2\u003e\u003cstrong\u003eIncludes Two Must-have RASA 8\" Imaging Filters\u003c\/strong\u003e\u003c\/h2\u003e \u003cp\u003eAlong with the RASA 8\" optical tube, this kit also includes the H-alpha H-beta OIII Imaging Filter and the Light Pollution Imaging Filter. This kit maximizes your RASA 8\" telescope's potential to capture stunning images under any sky conditions, ensuring precise targeting of specific celestial objects and optimal light transmission.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eLight Pollution Imaging Filter \u003c\/strong\u003e- This broadband filter effectively blocks specific wavelengths of artificial light while allowing the desired wavelengths of light emitted by celestial objects to pass through. When you add this filter to your RASA, you'll see vibrant, detailed celestial objects that \"pop\" against a dark sky background with excellent overall contrast. This filter blocks light from some of the most common sources of artificial and natural light pollution between 400 and 700 nm (i.e., the visible spectrum), including high- and low-pressure sodium-vapor streetlights, mercury-vapor streetlights, and natural airglow caused by oxygen in the atmosphere. \u003cbr\u003e\u003cbr\u003eUnlike some light pollution filters, Celestron's filter blocks only specific areas of the spectrum instead of wide regions. This helps to maintain image brightness and color balance. In addition, particular wavelengths associated with emission nebulae, such as H-α (656nm), H-β (486nm), OIII (496nm and 501nm), and SII (672nm), are highly transmitted, ensuring minimal loss of image brightness for those objects.\u003cbr\u003e\u003c\/p\u003e \u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/91079_RASA_8_Imaging_Kit_09_480x480.jpg?v=1709168591\" alt=\"Light Pollution Filter, RASA 8\"\u003e\u003c\/div\u003e \u003cp\u003e\u003cstrong\u003eH-alpha H-beta OIII (Hα-Hβ-OIII) Imaging Filter – \u003c\/strong\u003eThe specialized Hα-Hβ-OIII Imaging Filter, also known as the Nebula Filter, is a narrowband filter that allows very high transmission of select wavelengths of light from emission nebulae while blocking the rest of the spectrum. You'll immediately notice much higher contrast in your images, even from your light-polluted backyard! And since the transmission at the critical wavelengths is so high, the nebulae are not dimmed—only the background is made blacker.\u003c\/p\u003e \u003cp\u003eThe Hα-Hβ-OIII Imaging Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), and the Carina Nebula (NGC 3372). The transmission spectrum for the Hα-Hβ-OIII Imaging Filter is 85% or greater at key wavelengths (486nm, 496nm\/501nm, 656nm) and less than 0.5% transmission elsewhere. And while other nebula filters can't keep up with RASA's fast optics and end up blocking some of the the wrong wavelengths, this filter is engineered to pair perfectly with this ultra-fast f\/2 system.\u003cbr\u003e\u003c\/p\u003e \u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/91079_RASA_8_Imaging_Kit_10_480x480.jpg?v=1709168594\" alt=\"H-Alpha, H-Beta, OIII Imaging Filter\"\u003e\u003c\/p\u003e \u003cp\u003eBoth the Light Pollution Filter and the Hα-Hβ-OIII Imaging Filter are custom-engineered to work with RASA 8, so they won't block any of the \"good\" wavelengths, specifically targeting light pollution and other undesired wavelengths. The filters fit directly into the internal filter mount in RASA 8's front lens cell, where the optical window normally mounts. To use a filter, you first remove and replace the clear window with the desired filter.

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 \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 \u003cp\u003eAll refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings.

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 \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 \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 \u003cp\u003eWhen compared with “Hyperstar SCT” systems, the RASA 8 provides better optical performance and field illumination.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCGX: The Ideal Platform for RASA\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe CGX is the culmination of Celestron engineers’ decades of experience in equatorial mount design, incorporating feedback from imagers worldwide. Combined with the RASA 8, it is a state-of-the-art deep-sky astronomical imaging system.\u003c\/p\u003e \u003cp\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\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\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\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\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\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\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\u003eThe NexStar+ also has dozens of other functions to control every aspect of the mount’s behavior. These include:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMultiple ways to align the mount to the night sky\u003c\/li\u003e \u003cli\u003eAdjustable slew rates up to 5°\/second\u003c\/li\u003e \u003cli\u003eNorthern or Southern hemisphere compatibility\u003c\/li\u003e \u003cli\u003eAdjustable autoguiding rates\u003c\/li\u003e \u003cli\u003eHibernate mode so the mount can be powered down without loss of alignment\u003c\/li\u003e \u003cli\u003eContinual firmware development, with new features added regularly\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn addition to the autoguider port, the CGX 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 (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\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\u003e\u003cstrong\u003eReady for Remote Imaging\u003c\/strong\u003e\u003c\/p\u003e \u003cp\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\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\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\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\u003eIn summary, the CGX and RASA 8 together are a top-tier imaging system built for performance and ease of use.

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 \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 \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 \u003cp\u003eWhen compared with “Hyperstar SCT” systems, the RASA 8 provides better optical performance and field illumination.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCGEM II: An Excellent Platform for RASA\u003c\/strong\u003e\u003c\/p\u003e \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 \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 \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 \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 \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 \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 \u003cp\u003eThe NexStar+ also has dozens of other functions to control every aspect of the mount’s behavior. These include:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMultiple ways to align the mount to the night sky\u003c\/li\u003e \u003cli\u003eAdjustable slew rates up to 5°\/second\u003c\/li\u003e \u003cli\u003eNorthern or Southern hemisphere compatibility\u003c\/li\u003e \u003cli\u003eAdjustable autoguiding rates\u003c\/li\u003e \u003cli\u003eHibernate mode so the mount can be powered down without loss of alignment\u003c\/li\u003e \u003cli\u003eContinual firmware development, with new features added regularly\u003c\/li\u003e \u003c\/ul\u003e \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 \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 \u003cp\u003eTransporting the entire system to a dark site is not a problem either. The optical tube, mount head, tripod, counterweight bar, and counterweight all disassemble, with no tools required, into separate manageable pieces.\u003c\/p\u003e \u003cp\u003eIn summary, the CGEM II and RASA 8 work well together to attain stunning imaging results with minimal hassle.

This easy-to-install RA motor drive compensates for the Earth’s rotation, so the telescope tracks a star’s movement through the night sky from east to west.  When the telescope mount is properly polar aligned and the RA drive is attached and running, the user need only make occasional adjustments in declination (Dec) to keep an object in the eyepiece for long periods of time.  The Celestron single-axis motor drive runs on a 9V battery, so there are no cords to get in the way.  The drive can be used in either the Northern or Southern Hemisphere.  To change hemispheres (reverse the motor’s direction), simply by flip the N\/S switch on the face of the motor drive.  It is also simple to change the speed of the motor.  A “Speed Rate Regulator” knob is located just under the power indicator and can be turned in either direction to slow down or speed up the motor.  Since solar system objects like the Moon and planets move through the sky at different rates than deep-sky objects do, this gives you the ability to match the motor’s speed to the particular type of object you are observing.  \u003c\/p\u003e \u003cp\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/astromaster_130_90_motordrive_large.gif?v=1505422267\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eStarry Night Software\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eDownload Celestron’s Starry Night Software and learn about the night sky, celestial objects, and how to plan your next observing session.
