The GSO 10" f/4 Carbon Photo-Newton optical tube assembly is an astrograph designed for deep-sky astrophotography, based on a Newtonian reflector with a parabolic primary mirror of 250 mm diameter. The full-length carbon fiber tube provides high mechanical rigidity and excellent focus stability under temperature variations, which is particularly important during long imaging sessions.

Key features

• 250 mm (10") aperture and f/4 focal ratio
• full-length carbon fiber tube with high thermal stability
• parabolic primary mirror manufactured by GSO (Taiwan)
• rack-and-pinion focuser designed for heavy imaging equipment, compatible with ZWO EAF motor focuser
• active primary mirror cooling – 3 fans
• collimatable primary and secondary mirror cells
• monolithic CNC-machined secondary mirror spider
• internal baffles to reduce stray light
• two Losmandy-type mounting rails to increase rigidity and facilitate balancing

Items included

• GSO 10" f/4 Carbon Photo-Newton optical tube assembly
