36 CM ROWE-ACKERMANN SCHMIDT ASTROGRAPH

A breakthrough 36 cm aperture, f/2.2 optical system designed for professional applications that require both a wide field of view and resolution, such as space surveillance and other scientific applications

4-element lens group utilizes extra-low dispersion (ED) glass for images free of false color, coma, and field curvature, the Rowe-Ackermann Schmidt Astrograph (RASA) 36 cm is also an excellent choice for advanced astroimaging

60 mm optimized image circle maintains pinpoint stars to the far corners of the largest available sensors

Extended spectral range takes advantage of sensor response in the 700-900 nm range, allowing a brighter overall signal to be detected

Redesigned focusing system minimizes focus shifting or other unwanted motion of the primary mirror, enabling easy and stable focus
