RASA 8" - Rowe-Ackermann Schmidt Astrograph
Rasa 8" DiagramThe transportable astrograph from Celestron, the 8" Rowe-Ackermann Schmidt Astrograph (RASA), can capture spectacular deep-sky wide-field images in seconds. This incredibly fast f/2.0 system is the perfect telescope for modern astronomical CMOS color cameras, smaller CCD cameras and mirrorless cameras.
Thanks to the large focal ratio and the patented optical design, you can produce sharp, detailed images and in many cases completely dispense with an autoguider. With a weight of only 7.7 kg (17 pounds), it is easy to transport the 8" RASA to even the most remote locations.
RASA performance for everyone
The 8" RASA is a telescope designed purely for photography, providing a flat field of view with no optical aberrations to show extremely sharp stars over a wide field of view. It provides astronomical images with impressive "depth" and avoids the problems typically associated with longer focal length (and slower focal ratio) instruments.
The latest addition to the RASA family is a much more portable and affordable 8" aperture version of the RASA 11, which was launched in 2014 to great acclaim. With the 8" RASA, the benefits of the RASA design are now available to a wider range of astrophotographers. It shares many features with its "big brother" RASA 11, including the integrated cooling system, the internal filter holder and the robust CGE dovetail mount.
The 8" RASA is designed exclusively for photography and cannot be used visually. The focal plane is located at the front of the optical system, so the telescope cannot accommodate a conventional eyepiece.
Shorter exposure times and virtual "real time" observation
As it is an f/2.0 optical system, astrophotographers can use shorter exposure times to capture details in faint objects. In combination with sensitive cameras and the right "live stacking" software, the 8" RASA also makes near-live observations possible: you can instantly view and stack the images on a computer, making them brighter and more detailed than with the naked eye - even compared to much larger telescopes!
As shorter exposure times are possible, your mount does not have to track with high precision over long periods of time. The relatively short focal length of 400 mm of the 8" RASA further reduces the tracking requirements. In many cases, autoguiding is not necessary. With a weight of only 7.7 kg (17 pounds), this telescope fits perfectly with a large number of commercially available mounts.
Ultra-stable focusing system
With the introduction of the 8" RASA, Celestron introduces a new focusing mechanism that reduces the backlash of the primary mirror when focusing, slewing or tracking the astrograph. Focusing is easier, more accurate and more stable than ever. The key to this ultra-stable focusing system is two sets of precision bearings that are precisely aligned and tested during assembly for optimal results.
Unique optical design
The patented RASA design (US 2016/0299331 A1) consists of a Schmidt plate, primary mirror, lens group and optical window. The lens group consists of four elements and uses rare earths. In contrast to many other telescopes, which only perform well in visible light (400-700nm), the 8" RASA is designed for a wider spectral range, from 390-800 nm. This allows more light from celestial objects to be collected and imaged sharply.
With many optical systems, it makes no difference to the image quality whether an additional flat glass such as a filter is used. The situation is different with extremely fast systems such as the RASA. Our developers have solved this problem by providing the RASA with an optical window that can be removed and replaced with a filter. This means that the image quality remains at the highest level even if you use a filter or the camera has its own optical window. Celestron offers a filter against light pollution which was specially developed for the 8" RASA and which replaces the optical window.
All refractive optical surfaces are StarBright-XLT coated, the primary mirror has an improved aluminum coating. This ensures high transmission for the entire system. Compared to the HyperStar system for Schmidt-Cassegrains, the RASA 8 delivers better optical performance and superior illumination.
Developed for the most modern cameras
In contrast to the larger RASAs, which are optimized for DSLR and large CCD cameras, the 8" model was developed for astronomical CMOS colour cameras, smaller CCD cameras and mirrorless cameras. The telescope does not work with standard DSLR cameras due to the available back focus. It is optimized for sensors with a diagonal of up to 22 mm and still offers good performance on sensors with a diagonal of up to 32 mm. The APS-C format sensors used in many mirrorless cameras are a good choice. 42 mm full-frame sensors also work in principle, but performance visibly degrades at the edges of the sensor and field illumination is reduced. Furthermore, we do not recommend combining the RASA 8 with a camera body with a diameter of more than 10cm.
The following cameras are compatible with the RASA 8 via adapter:
Astronomical CMOS/CCD camera with C-mount
Astronomical CMOS/CCD camera with M42 thread connection
Astronomical CMOS/CCD camera with other connection
Mirrorless Canon with APS-C sensor
Mirrorless Sony with APS-C sensor
Mirrorless Canon and Sony cameras with full-frame sensor are also compatible with the RASA 8, but are not optimized over the entire sensor.
DSLR cameras are not compatible.
The scope of delivery includes a C-mount adapter and an M42 adapter, further adapters for other compatible cameras are available separately.
To use an astronomical CMOS/CCD camera with an M42 threaded connection, you need an M42 adapter ring, which is available separately.
CGX: The ideal platform for RASA
The CGX is a robust equatorial mount that supports the RASA 8 safely and vibration-free. The mount has been made more compact so that the instrument load is closer to the R.A. axis, which enables short reaction times even with heavy payloads. With a payload of 25 kg, the CGX can easily carry the 7 kg of the RASA 8 as well as a camera and any accessories. The RASA 8 is connected directly to the CGX using the dovetail mounting rail (CGE standard).
The sturdy, height-adjustable tripod has steel tripod legs with a diameter of 2" and a wider tripod head for more stability. The markings on the tripod legs make it easy to adjust the height quickly.
The mount is packed with features that make working with the 8" RASA easy. The fully computerized mount automatically tracks any of the 40,000+ astronomical objects selected and approached from the NexStar+ hand controller database.
The low starting resistance ensures that the motors run smoothly, while the integrated optical encoders ensure accuracy. The motors are connected to the worm gearboxes via toothed belts to reduce gear backlash when the motor changes direction. The steel worm gear is precision-beared and sprung against a brass worm wheel to ensure a smooth, backlash-free and connectionless drive.
To track objects in the night sky, the mount must first be polar aligned. Thanks to the built-in All-Star Polar Alignment, polar alignment is no problem, even without looking at the celestial pole - the polar finder is superfluous (a polar finder is optionally available.) The best thing about it is that the setup can usually be completed in less than 15 minutes, even without a clear view of Polaris.
All mounts have a certain amount of "periodic worm error" caused by tiny gear irregularities. To prevent this, the CGX has a permanent periodic error correction (PPEC). For this purpose, the periodic error is recorded and saved once, after which the control software of the hand controller automatically corrects the periodic worm error. If even greater tracking accuracy is required, the mount also has a special autoguider connection to connect an autoguider camera directly to the mount.
The best conditions for observation are when celestial objects are at their highest point in the sky, the so-called meridian. But some equatorial mounts have difficulty tracking near the meridian because they have to perform a "meridian flip": The telescope must be slewed around. The CGX does not suffer from this problem as tracking beyond the meridian is possible and no meridian flip is required. The mount tracks up to 20º above the meridian. It also supports the SkyPortal WiFi and the StarSense AutoAlign module.
The NexStar+ hand controller also has dozens of other functions. These include:
Multiple methods for aligning the mount to the night sky
With slewing speeds of up to 5° per second, you can quickly target any object in the database.
Usable in the northern and southern hemispheres
Autoguider port
Sleep mode, so the mount can be turned off without losing alignment.
Firmware updates possible via the Internet
In addition to the autoguider port, the CGX also has other ports. The hand control has a USB 2.0 port to control the mount with a PC and optional third-party software. There are also 2 AUX ports on the mount for optional accessories such as StarSense AutoAlign or the SkyPortalWiFi module.
Transporting the entire system is also no problem. The telescope, mount head, tripod, counterweight rod and counterweight(s) can be separated from each other without tools and transported individually. Thanks to the large carrying handles, it is even easier to transport than a comparable, slightly lighter classic equatorial mount!
Ready for remote imaging
As a photo mount, the CGX is just as suitable for mobile use as it is for remote operation. One of the most critical problems in remote operation is the accidental collision of the optical tube with the mount. This not only ruins an image and requires realignment of the controls, but can also damage expensive equipment. With the CGX there is no such danger: internal sensors ("switches") automatically bring the mount into the home position and prevent it from moving too far during panning and hitting something. The internal cabling also ensures safety: all connections (power, hand controller, AUX and autoguider) are in the base of the mount and do not move with it.
For remote operation, there is a USB 2.0 socket for direct connection to a PC. The Celestron PWI telescope control software, developed in collaboration with PlaneWave Instruments, has an intuitive graphical user interface and offers an excellent solution for remote operation. Multipoint GoTo modeling, plate solving and focuser control are just some of the functions that you normally have to retrofit for remote operation - with the CGX, this software is included in the scope of delivery. The hand controller is not necessary for this.
To summarize, the CGX and RASA 8 together form a first-class system designed for performance and ease of use. This set is perfect for shooting in your own backyard or in a remote dark location, whether you are near the telescope or on the other side of the world.
