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.

The adapter extends a male T2 thread to M48x0.75 (2") filter thread without increasing the length.

• Female thread: T2 - M42x0.75
• Male thread: 2" filter thread - M48x0.75
• Length: only 2.5 mm - the mechanical length is optically not effective, as the adapter is completely sunken in the connection adapter

TS Photoline APO refractor wit 72 mm aperture and fast f/6 focal ratio, a great travel telescope for observation and astrophotography.

• ♦ Powerful, aberration-free apochromatic refractor with 72 mm aperture and 432 mm focal length.
• ♦ Fast focal ratio: f/6
• ♦ FPL53 doublet objective (Ohara Japan), air-spaced - additional lanthanum element, so no chromatic aberration
• ♦ 2.5" dual-speed rack-and-pinion focuser - ball bearing mounted for maximum load with M63x1 female thread for adaptions
• ♦ 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!

TS T2 M42x0.75 extension tube - 10 mm length - with T2 threads at both ends.

♦ Optical length: 10 mm

♦ Male thread length: 4 mm

♦ Female thread length: 9 mm

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
• Illuminated and corrected image field of 44 mm diameter - usable up to full format
• 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

Versatile dovetail bar for telescope attachment to mounts with Losmandy level saddle plate

• Length: 180 mm
• Very solid in spite of its weight of only 434 grams
• Slotted holes, thread bores and countersunk bores allow a wide range of adaptations
