GSO Newton 200/800 Monorail

GSO Newton 200/800 Monorail

The GSO Newton 200/800 Monorail is a fast Newtonian reflector telescope, specifically designed for astrophotography. Its 200 mm BK7 parabolic primary mirror with 94% reflectivity delivers bright and high-contrast images. The short f/4 focal ratio allows for reduced exposure times, making it ideal for capturing deep-sky objects.

The 2" Monorail focuser with 1:10 micro-reduction ensures precise focusing, even with heavy loads like CCD/CMOS cameras. The robust mechanical design guarantees optimal stability, essential for long-exposure imaging.
