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.
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.
Another special feature of the RASA 1100 V1 is the focusing - bronze bearings reduce image shift, the 10:1 Feather-Touch Micro-Focuser allows the most precise fine focusing adjustment!
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.
It is not only important which telescope you buy, but also where you buy it.
