Product description

More about the series RASA...

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.
