TS Optics Photon N 200/1000 OTA

Description

Resolve fine details in lunar crater chains and track distant spiral galaxies through the TS Optics Photon N 200/1000 OTA large aperture newtonian reflector optical tube assembly. Operating at a versatile f/5.0 focal ratio with a 1000mm focal length, this 200mm (7.87 in) aperture instrument delivers a 0.58 arcseconds theoretical resolving power and reaches magnitude 14.2, gathering light for high-performance deep-sky astrophotography, faint galaxy auditing, and high-resolution planetary video imaging.

The optical system features a parabolic primary mirror made from low thermal expansion borosilicate glass, treated with enhanced aluminum coatings yielding 94% reflectivity with a protective SiO2 overcoat, with a 31.5% central obstruction by diameter (9.9% by area) from its 63mm secondary mirror. Housed in a solid rolled steel tube measuring 900mm in length with a 230mm outer diameter, the tube provides 65mm of back focus above the 2-inch visual back, optimized for DSLRs and cooled CMOS astronomy cameras with coma correctors. Fitted with a 2-inch Monorail dual-speed linear bearing focuser, this 8.80 kg (19.40 lbs) telescope covers a 44mm full-frame format when paired with optional TS-GPU coma correctors.

Key Features of TS Optics Photon N 200/1000 OTA

Built for amateur astronomers seeking significant 8-inch light-gathering capability in a durable steel chassis, this 200mm f/5.0 Newtonian combines a parabolic primary mirror with a dual-speed Monorail focuser. Its rear 12V cooling fan, CNC-machined tube rings, and 35mm visual extension tube provide a dependable platform on equatorial mounts.

Eight-Inch Borosilicate Primary & 94% Reflectivity Coatings

The 200mm parabolic primary mirror collects ample light to resolve faint extragalactic structures and globular cluster cores without chromatic aberration. Enhanced aluminum coatings with 94% reflectivity maximize photon throughput, supporting high-contrast visual and video magnifications from 28.6x up to 400x.

Heavy-Duty 2-Inch Monorail Track & Quick-Setup Rings

Holding imaging trains without mechanical deflection relies on a 2-inch Monorail focuser featuring a central stainless steel guide track and a 1:10 micro-reduction gear. An integrated 12V fan accelerates mirror cooling, while the included 35mm extension tube adapts easily between photographic and visual configurations on mount saddles.

• 2-inch Monorail dual-speed linear bearing focuser with 1:10 fine tuning to eliminate drawtube flexure
• Rear 12V cooling fan circulating ambient air to accelerate primary mirror thermal stabilization
• Heavy-duty rolled steel tube construction providing high mechanical stability and collimation hold
