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.

This low profile adaptor enables the connection of T2 accessories to adaptors with M48x0,75 male thread.

• Thread towards telescope: M48x0,75 - 2" filter thread (female thread)
• Thread towards camera: T2 - M42x0,75 male thread
• Optical length only 3,5 mm
• Combining the optical extension tube TSVF230 with the TSM48-T2 adaptor provides a Focal Adaptor from 2" to T2 - with no optical length!

Dovetail Bar - Losmandy Level - for GSO and AstroTech 8" Ritchey Chretien Telescope adaption for the 8" GSO and AstroTec RC and mounts with Losmandy level dovetail bar holder

In the box:

-- Losmandy Level dovetail Bar
-- 2 Spacer for the 8" AstroTech and GSO RC telescope

The 2" CCD compressor reduces the focal length of telescopes with the factor 0.67x, thus allowing significantly shorter exposure times.

• ♦ The focal reducer is perfectly suitable for RC telescope. It also works good with Celestron EHD or Meade ACF telescopes or with refractors up to the focal ratio F/9
• ♦ The image field of DSLR cameras up to APS-C format is illuminated - full illumination up to 29 mm
• ♦ Easy connection to the telescope via 2" barrel
• ♦ Optimal working distance from the M48x0.75 thread to the camera sensor is 85 mm - enough space for accessories like off-axis guider or filter wheel
• ♦ 2" filter thread at the telescope side

The 8" Ritchey-Chrétien is the perfect telescope for astrophotography, but it is also suitable for visual observation.

• ♦ Aperture 8" / 203 mm - focal length 1624 mm - focal ratio f/8
• ♦ Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
• ♦ Both mirrors made of fused silica for stable focus position
• ♦ 99% high-reflectivy coating on main and secondary mirror for an even brighter image and more contrast - special service from TS
• ♦ Quicker cooling down thanks to open construction and primary mirror ventilation
• ♦ Two Vixen style dovetail bars supplied - ideal for accessories like guiding scopes or a piggyback camera mount
• ♦ High-quality 2" dual speed MONORAIL focuser with 2" / 1.25" reduction adapter - motor focuser optionally available
