More about the series Advanced VX...
Digital Schmidt camera for wide angle astrophotography!
This astrograph makes it very easy to create stunning photos with a modern DSLR or astronomical CCD camera. The new optical design has a four-lens corrector, incorporating rare earth glass, which suppresses chromatic aberrations and other problems such as coma and field curvature. Never before has an astrograph in this price range delivered such optical quality and spot size over the entire image field. The design also allows for a very low vignetting.
- super-fast 11" f2.2 optics - sharply images APS format and is even optimized for sensor sizes up to a 70mm field diagonal.
- extremely short exposure times - the RASA Astrograph acquires images twenty times faster than at f10! Thirty seconds at f2.2 correspond to ten minutes at f10 - tracking control is hence superfluous!
- huge field of view - with a 620mm focal length, makes wide-angle shots a piece of cake and you and always have an overview
- excellent focusing mechanism - new bronze bearings reduce image shift, the 10:1 FeatherTouch micro-focuser allows highly precise focusing!
- innovative Features - quieter 12V MagLev fan reduces the cooling phase, keeps out dust and allows optimum air circulation in the OTA. Various adapters for popular camera brands are included. Back focus for the camera supplied adapters: 55mm, back focus for the front lens group: 69.26mm
RASA stands for Rowe-Ackermann-Schmidt Astrograph - Dave Rowe and Mark Ackermann are renowned optical instrument designers. Together, they hold numerous patents on their inventions. The RASA astrograph combines their expertise and experience.
Note: The RASA 800 doesn't work with regular DSLR cameras (because of a short backfocus). It is recommended to use the RASA 800 with mirrorless cameras or small dedicated CCD or CMOS astronomical cameras.
The Advanced VX is the ideal mount for mobile astrophotography using small to medium-sized telescopes! Telescopes up to around 14kg can benefit from the well-engineered functions of Celestron’s large parallactic mount. Thanks to PEC (Periodic Error Correction), the periodic error, which occurs in all mounts with classic worm gears, is strongly reduced, making long exposures possible. Additionally, you can follow objects far beyond the meridian, without instant switching being required. This means you can observe the most interesting part of the sky without interruptions. The Advanced VX also has a considerably wider base than its predecessor, which increases stability when carrying heavy loads. Improved motors have with high torque and can better compensate for small imbalances.
Experienced photographers will appreciate how easily this mount can be transported to dark observation spots. If you are just starting out with astronomy or astrophotography, the Advanced VX can help to make those first steps easier and provide you with good service for many years to come.
The mount takes Vixen-style dovetail rails or wider Celestron rails (CGE-style), but not 3” Losmandy rails.
