GSO Newton 154/600 F/4 optical tube

GSO 154mm F4 Newton Ota optical tube with 50.8mm Monorail focuser.

This GSO Newtonian offers essential advantages for astrophotography: a 2 "Monorail focuser with 1:10 reduction and sufficient backfocus to focus with the most common coma correctors.

The mirror is of high quality and can be used with profit even in high resolution.

2" Monorail focuser: perfect for both visual and photographic use.

Monorail system is an improved variant of the classic Crayford design, designed to offer better performance.

Visual use: offers contrasting images for excellent observations of the Moon and planets thanks to very fine secondary supports and high quality parabolic primary mirror.

Use in photography: suitable for astrophotography, allows the use of the coma corrector for point stars throughout the field.
