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 optics - extremely short exposure times - the RASA Astrograph acquires images twenty times faster than at f/10! Thirty seconds at f/2.2 correspond to ten minutes at /f10 - tracking control is hence superfluous!
- excellent focusing mechanism
- innovative Features - quieter 12V MagLev fan reduces the cooling phase, keeps out dust and allows optimum air circulation in the OTA.
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.
The new version V2 is equipped with the Ultra Stable Focus System (USFS). It is focused by moving the primary mirror. So that there is no image shifting and tilting, focussing is controlled via a precise linear ball bearing system.
Focussing can be achieved using the Celestron focussing motor.
Which cameras is the RASA 1100 suitable for?
This Schmidt astrograph offers an image circle of fully 43mm, so you get pin sharp stars even on large sensors - up to 52mm is usable. This large illuminated image circle and a focal length of only 620mm make this the perfect instrument for astrophotography of large areas of the night sky and extended astronomical objects. For example, you can create mosaics of the entire night sky or look for varaible stars, supernovae or comets.
