TS-Optics UNC 200/1000 mm f/5 Newtonian with Carbon Fiber Tube and Optics Test

The UNC Newtonian series from Teleskop-Service offers an alternative to the Far East Newtonians

With these telescopes you do not have to make any compromises. UNC stands for Universal Newtonian telescope with Carbon tube. Each UNC Newtonian is individually manufactured for you and optimized according to your wishes - a telescope Made in Germany!.

The 8" f/5 UNC Newtonian is a universal telescope for stationary and transportable use. At moon and planets mostly only the atmosphere limits the resolution of the telescope. However, the Newtonian is fast enough to successfully photograph nebulae and galaxies. The UNC is already well supported by moderate mounts like the Skywatcher EQ5 or the Celestron Advanced VX, even for photographic applications.

The advantages of the TS UNC Newtonian telescopes:

High-quality carbon tube with highest stability - individual manufacture.

Optimized focus position as desired and thus also best possible illumination

Primary mirror cell and secondary mirror cell improved by Teleskop-Service

Easy collimation of primary and secondary mirror - by hand, without tools

The edge of the secondary mirror is blackened

TS UNCN2-G2 2" rack and pinion focuser with M54x0.75 intermediate thread

The secondary is attached to the secondary mount with correct offset by Teleskop-Service

94 % reflectivity on primary mirror and secondary mirror for a brighter image

Diffraction limited primary mirror - each telescope is tested on our optical bench before shipment

Every UNC Newtonian is darkened inside

The tube inner side of our UNC Newtonian telescopes is darkened. This prevents reflections and provides better contrast. The TS "Black" anti-reflective paint or a velour film is used. The result is a matte black tube interior. Velour film and the TS "Black" have a similar effect and darken better than the commonly used chalkboard paint.

The illustration shows how dark the anti-reflective paint is. The diagram (at the images at the top of this page) shows the direct comparison chalkboard paint and antireflective paint.

The carbon tube - finest precision work

The carbon tube is extra solid and completely reinforced, not only around the focuser. This makes the tubes much stiffer and the adjustment stability is high. The openings for the secondary are precisely fitted with turned mating parts, so we ensure that the secondary spider vanes are correct and the telescope produces perfect spikes right from the start.

Focus position optimized for astrophotography:

With the standard focuser UNCN2-G2 you get 85 mm working distance, this even allows the use of focal reducers or a binoviewer with moderate glass path compensation. For standard correctors like the Baader MPCC or the TS-Optics MAXFIELD corrector we recommend the 20 mm spacer, which comes between the focuser. This gives you 65 mm backfocus.

For visual observation you need a 2" extension tube - item # TSV235.

The 2" TS UNCN2-G2 RAP focuser:

A core component of the TS UNC-Newtons is the modern TS UNCN2-G2 focuser. The focuser builds up only 58 mm from the tube edge and still carries heavy cameras and accessories without tilting. The focuser is superior to conventional Crayford focusers.

high stiffness with extremely short length

exact 1:10 dual-speed gear - for perfectly focused astrophotographs

Adjustment is decoupled from the ball bearing - a clear advantage over Crayford focusers

Upgradable with motor focus - with the TS motor focus advantage: manual adjustment possible with mounted focuser

Ball bearings are adjustable, so the focuser can be adjusted perfectly - but we deliver the focuser already optimally adjusted.

Screw connection of the accessories possible - the 2" receptacle can be unscrewed, then an M54x0.75 female thread is available.

Parabolic Primary Mirror:

Newtonian primary mirrors are free of strain and typically provide an image that is significantly better than diffraction-limited. The surface is coated with an enhanced 94% reflection coating and a protective quartz layer. The primary mirror has a central mark as an alignment aid.

Quality guarantee through optics test by TS:

After assembly, each Newtonian telescope is checked by our technical department to ensure that the optics and mechanics work together smoothly.

The mechanics are checked and the focuser is adjusted to the optimum setting.

The optics are collimated and the result is checked on the optical bench.

A complete optical test is performed and included with the telescope (star images and Ronchi grating images on the optical bench in autocollimation).

Only then are the telescopes transferred to the warehouse or prepared for shipping.

Before shipping, the primary mirror with the cell is removed from the tube and packed separately. This way we guarantee a safe shipment and avoid unnecessary transport damages.
