Orion CT12 300/1200 Carbon Newtonian OTA

Description

Combining a fast f/4 focal ratio with a 300mm (11.81 inches) 1/10 PV Suprax mirror, the Orion CT12 300/1200 Carbon Newtonian OTA deep-sky telescope provides 0.39 arcsecond Dawes resolving power. Crafted in the United Kingdom by Orion Optics UK, this 1200mm focal length optical tube assembly reaches magnitude 14.2 for observatory-scale imaging campaigns.

The Orion CT12 300/1200 Carbon Newtonian OTA features a precision-annealed Suprax parabolic primary mirror verified by a Zygo interferometer report, treated with 97% reflective Hilux multi-layer coatings. Its structural twill carbon fiber tube incorporates internal anti-reflective coating, a CNC-machined 9-point cell with micro-adjusting collimation bolts, and a 2-inch dual-speed Octoplus Crayford focuser. Weighing 15.00 kg (33.07 lbs), this 12-inch reflector OTA ensures high thermal stability and rigid focus retention on equatorial mounts.

Key Features of Orion CT12 300/1200 Carbon Newtonian OTA

12-Inch 1/10 PV Zygo-Verified Suprax Parabolic Optics

The 1/10 PV Suprax primary mirror collects massive photon volume while eliminating spherical aberration across wide visual and photographic fields. With a 2-inch Octoplus focuser, this fast f/4 Orion Newtonian OTA supports magnifications from 43x up to 600x.

2-Inch Octoplus Crayford Focuser & Carbon Fiber Chassis

Preventing tube flexure and focus shift during long observing runs requires high-grade composite engineering. The Orion CT12 features a woven carbon fiber body shell that remains thermally inert across cold night cycles. Its 2-inch dual-speed Octoplus Crayford focuser provides smooth, backlash-free focusing for high-resolution visual observing and deep-sky imaging.

• 2-inch dual-speed Octoplus Crayford focuser with 10:1 planetary precision micro-drive
• Thermally inert twill carbon fiber shell weighing only 15.00 kg for easy mount handling
• CNC-machined aluminum support rings fastened to a heavy Losmandy-style dovetail bar
