Ritchey-Chrétien optical tube TS-GSO RC 16 Truss

Ritchey-Chrétien optical tube TS-GSO RC 16 Truss

The TS GSO Ritchey-Chrétien RC 16" f/8 optical tube is an astrograph that will be an astrophotographer's dream. It is a perfect telescope for observatories. Its results are spectacular with large format sensor cameras.

Its performance will be evident when working with EQ8 or similar mounts (see the recommended mounts section below).

Main general characteristics:

• Diameter: 16" / 406 mm
• Focal length: 3250 mm
• Focal ratio: f/8
• Carbon fiber truss format with 2 dovetail type dovetails Losmandy
• Dielectric treatment with high reflectivity of 99% on primary and secondary mirrors
• Large corrected field without the need for additional correctors.
• 3" MONORAIL focuser for greater stability
• Focusing can be adjusted (tilt) independently of the primary mirror

• The carbon fiber truss format eliminates the effects of expansion and contraction
• Without corrector the RC 16" offers a wide flat field with a diameter of approx. 70mm.
• The TS GSO RC 16" has a backfocus of 306mm (from the back plate).
• The primary and secondary mirrors are hyperbolic and made of low expansion Quartz. Dielectric treatment with 99% reflectivity and specific anti-scratch treatment.
• The RC 16" tube incorporates 3 small fans in the rear cell to reduce turbulence caused by the thermal gradient.
• The primary mirror is blocked so that no image shifting can occur.
