In many cases, autoguiding is not necessary. The relatively short focal length of 400 mm of the 8 "RASA additionally reduces the requirements for tracking. Since shorter exposure times are possible, your mount does not have to track with high precision over longer periods of time. In combination with sensitive cameras and the right "live stacking" software, the 8 "RASA also enables almost live observations: You can view and stack the images immediately on a computer, making them brighter and more detailed than with the naked eye - even compared to much larger telescopes! Shorter exposure times and virtual "real time" observationīecause it is an optical f / 2.0 system, astrophotographers can use shorter exposure times to capture details in weak objects. The focal plane is located on the front of the optical system so that the telescope cannot accommodate a conventional eyepiece. The 8 "RASA is designed for photography only and cannot be used visually. With the 8" RASA, the advantages of the RASA design can now be used by a large number 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 latest addition to the RASA family with an 8 "opening is a much more portable and affordable version of the RASA 11, which was launched with great success in 2014. It enables astronomical images with an impressive" depth "and avoids the problems that typically arise Instruments with a longer focal length (and a slower aperture ratio) occur. The 8 "RASA is a photography-only telescope that provides a flat field of view with no optical aberrations and thus shows extremely sharp stars over a large field of view. Weighing just 7.7 kg (17 pounds), it is easy to transport the 8 "RASA to the most remote locations. Thanks to the large opening ratio and the patented optical design, you can create sharp, detailed images and in many cases completely do without an autoguider. This incredibly bright f / 2.0 system is the perfect telescope for modern astronomical CMOS color cameras, smaller CCD cameras and mirrorless cameras.
