TS 10" f/4 UNC Newtonian - Carbon Tube on NEQ6 Synscan

The UNC series from Teleskop Service is THE alternative to Newtonians from far east but also to high-end, high-cost instruments. UNC is a price effective telescope line without compromises. UNC stands for Universal Newtonian Telescope with Carbon tube. Individually optimized, Made in Germany!

The 10" f/4 UNC Newtonian is a transportable telescope for astrophotography. The fast focal ratio f/4 allows very deep galaxy and nebular images with short exposure times.

The mount

The Skywatcher mount NEQ6 SynScan GoTo holds this Newtonian with very good stability. Especially astrophotographers loves the quality of the EQ6 because of the precise tracking and the accurate positioning. You will always have the object on the camera sensor.

• GoTo Drive System - latest version
• Autoguiding connection
• Stainless steel tripod and two counterweights.

The advantages

• High quality carbon fibre tube, individually manufactured in Germany
• Optimized focus position according to customer´s demands for best field illumination
• Main and secondary mirror cell improved
• Easy collimation without tools
• Blackened secondary mirror edges
• TS UNCN2 2" Crayford focuser - one of the best systems in its class
• Secondary mounted with correct offset
• Diffraction limited system

Anti reflex painting for maximized contrast

For our UNC Newtonians, we use Berger Anti-Reflex paint. As effective as dark black velours foil, it does not gather dust which lands on the mirror and has a weight advantage.

Three focus positions possible

1. Astrophotography with normal Coma Correctors - 65 mm distance from the 2" connection of the focuser (STANDARD Version)
   This version is perfect for nearly all 2" Newtonian coma correctors like the Baader MPCC, TS Komakorr, ASA Quattro, etc. For visual observing, you will need a 35 mm 2" extension tube TSV235.
2. Astrophotography with ASA 2" Reducer/Corrector - 90mm distance from the 2" connection of the focuser
   This version is made for the famous ASA Reducer and Corrector. The focal ratio will reduced from f/4 to f/2.8 with really good field correction. This position is also made for the very long GPU corrector.
3. Optimized for visual observing and TeleVue Paracorr VIP-2010 - 35mm distance from the 2" connection of the focuser
   This version is perfect for amateur astronomers looking for a telescope for visual observing. For this version a 63 mm secondary mirror can also be chosen.

The Crayford focuser

One crucial part of the TS UNC Newtonians is the TS UNCN2 focuser. Although needing only 50 mm back focus, the focuser accepts heavy cameras without tilting. With this focuser, we have been able to optimize the focus position above the tube for maximum illumination.

• includes precise 1:10 dual speed transmission
• the focuser holds also heavy cameras and acessories
• upgradable with TS motorfocus system - manual use still awailable
• adaption via 65 mm thread for cameras or 2" for eyepieces

Mirror fan

Instead of chosing exotic and incredibly expensive mirror substrates we have chosen to equip this telescope with a BK7 primary mirror and a cooling fan to accelerate cool-down time to ambient temperature. Until a mirror is properly cooled down, it will create currents of warm air that will deteriorate the image - no matter which mirror substrate is used. Only after the mirror has cooled down this effect stops.

Parabolic primary mirror

The very precisely figured parabolic primary mirror of this telescope is not made of cheap float glass, but rather of BK7 optical glass that is free of internal stress. Thermal properties are generally better than float glass. At the same time the mirror is way more affordable than more exotic primary mirror substrates that in our opinion hardly bring any advantage at all. For easier collimation, the mirrors are properly center marked.

You receive an individually in auto collimation tested telescope. UNC Newtonian telescope are handmade telescope "made in Germany".
