The Opticstar ARX200 Astrograph is a wide/flat field imaging instrument that been designed for the
purpose of astro-imaging and astrometry.
It can be used in conjunction with a camera to capture images of the same section of the sky over
days or weeks apart for the purpose of discovering ‘new’ objects including novae, variable stars,
asteroids, meteors and comets. Image data can then be compared to reveal changes in brightness,
movement or new objects that have entered our Solar system.
