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.

• ♦ Retractable dew cap - the apo even fits into the hand luggage
• ♦ CNC tube rings with versatile dovetail bar - EQ5 style and with photo tripod connection.
• ♦ Findershoe on the focuser is included
• ♦ Weight only 2.18 kg - transport length only 31 cm

Collimating your refractor telescope is quick and easy when you use this 1.25" Cheshire collimating eyepiece. You see in seconds the collimating situation of the telescope, you also can use the Cheshire on newtonian telescopes.

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.

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!

The powerful 6-element Apo with 76 mm aperture and 342 mm focal length has been developed by Teleskop-Service for astrophotography.

• Aperture 76 mm
• Focal length 342 mm
• High focal ratio f/4.5 for short exposure times

• Multi-coated FPL53 APO Triplet lens, free from false color
• Screwed 3-element ED corrector with 55 mm working distance from the M48 camera connection
• 3" RAP rack and pinion focuser with 360° rotation possibility
• 2" and 1.25" connection for observation are included - 1.25" and 2" accessories can be used
• 2" nebula filters can be screwed into the corrector
• CNC tube rings with handle, viewfinder shoe and V-style dovetail bar are included in delivery
• The handle offers adaptation options for guide scope or camera

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

High-quality 2" focuser for astrophotography and visual observation with Ritchey-Chrétien telescopes - holds acessories up to 6 kg.

• Oversized ball bearings and V2A stainless steel bearing surface for maximal load with smooth adjustment
• 2" and 1.25" clamping by brass compression ring
• D=65 mm connection thread for threaded adaptions for astrophotography
• Dual speed with gear wheel for motor focus - friction cluth integrated - motor focus is optional
• Trouble-free adaption to TS-Optics, GSO, AstroTec.. RC telescopes via the M90x1 connection thread (female) at the telescope side
• Minimal height with base is 91 mm
• Drawtube travel is 30 mm
• Motorized focusing is possible - see optional accessories

The adapter allows connecting 2" accessories to adapters, correctors and focusers with male M48x0.75 thread

• Telescope-sided connection: M48x0.75 thread (female)
• Eyepiece-sided connection: 2" receptacle (female)
• Length: 40 mm
• Locking via 2 knurled screws and brass compression ring

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
