A breakthrough 36 cm aperture, f/2.2 optical system designed for professional applications that require both a wide field of view and resolution, the Rowe-Ackermann Schmidt Astrograph (RASA) 36 cm is ideal for space surveillance and other scientific applications.
With a 4-element lens group featuring extra-low dispersion (ED) glass for images free of false color, coma, and field curvature, RASA 36 cm is also an excellent choice for advanced astroimaging.
New Ultra-Stable Focus System (USFS) minimizes focus shift, mirror flop, and any other unwanted motion of the primary mirror, enabling easy and dependable focus.
60 mm optimized image circle maintains pinpoint stars to the far corners of the largest available sensors.
An extended spectral range takes advantage of sensor response in the 700-900 nm range, allowing a brighter overall signal to be detected.
