The TS Superflat GPU coma corrector is one of the best correctors for astrophotography through fast Newtonians.

• 4-element coma corrector for excellent imaging in the field and on the axis.
• Designed by Gyulai Pal in Hungary (GPU-Optics)
• Perfectly suitable for Newtonian telescopes with focal ratios of f/4 - provides very good results from f/3.5 to f/6.
• Very tolerant against tilting.
• Focal length is not changed.
• Camera connection through M48 thread.
• For better stability and accuracs, the corrector can be screwed to the focuser. Connection adapters for cameras and focusers are available.

TS 8" f/12 Cassegrain telescope with fused Quartz mirror and only 33% obstruction - the ideal alternative to a Schmidt-Cassegrain

• Aperture 8" - 203 mm
• Focal length 2436 mm
• F-ratio f/12
• Large illuminated image field with 45 mm diameter
• Hyperbolic secondary mirror and parabolic primary mirror made of Quartz glass for stable focus position
• 99% reflection on primary and secondary mirror for an even brighter image
• Quick temperature adaption due to open design
• Pure reflective system without Schmidt plate or meniscus lens - fully suitable for Infrared
• Only 33 % linear obstruction - very well suited for visual astronomy
• 2" MONORAIL focuser with micro-gear reduction and 1.25" reduction are included
• M90 extension tubes for trouble-free focusing with almost any accessories included
• Internal baffles for higher contrast
• Losmandy style dovetail and Vixen/EQ5 style dovetail for trouble-free adaption to all popular mounts
• Finder-scope shoe is also included
• Very economically priced, compared with other classical Cassegrains

The TSRCKOLLI collimator was developed for Ritchey-Chrétien telescopes, but also for all other types of telescopes, like refractor, Newtonian or SC Cassegrains - made in Europe

• The corrector allows the collimation of almost all optical systems with high accuracy.
• Suitable for all 2" receptacle with precice 2" barrel to avoid tilting
• LEDs are powered by 2 normal 1.5V AA batteries (batteries are not included)
• We recommend the collimator mainly for RC telescopes, Cassegrains and Schmidt Cassegrains as long as they have a center mark on their secondary mirror. So a top collimation state of the telescope can be reached even at daylight.
