The TS Optics UNC Newtonian series offers an alternative to Newtonians made in the far east. With these telescopes you do not have to settle for any compromises. UNC stands for Universal Newtonian telescope with Carbon tube. Each UNC Newtonian is individually manufactured for you in Germany.

These Telescopes are specially made to order.

The 6" f/6 UNC Newtonian is a compact and transportable all-round telescope. It is ideally suitable for visual observation and astrophotography. Astrophotographers will appreciate fine stars because of the small secondary mirror and in combination with suitable coma-correctors, deep-sky photography are possible in a relatively short time.

The advantages of the TS UNC Newtonian telescopes:

• High-quality, German-made high quality carbon tube.
  
• 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 Pre-attached to the secondary mount with the correct offset.
  
• 94% reflectivity on primary mirror and secondary mirror for a brighter image
  
• Diffraction limited primary mirror - each telescope is tested on an optical bench before shipment

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, ensuring that the secondary spider vanes are correct and the telescope produces perfect spikes right from the start.

Focus position optimized for astrophotography:
The focus point is 135mm above the tube. This allows you to use different focusers and still have a comfortable working distance. With the standard focuser UNCN2-G2 you even get 80mm working distance, this even allows the use of focal reducers or a binoviewer with moderate glass path compensation. For standard correctors we recommend a 20mm spacer, which sits between the focuser. This gives you 60mm backfocus.

Note: For visual observation you need a 2" extension tube - Click here.

• 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 58mm 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
  
• Threaded connection of accessories is possible - the 2" receptacle can be unscrewed, then an M54x0.75 female thread is available.

Parabolic primary mirror:
Newtonian primary mirrors made of fused silica are free of strain and provide an image that is usually much better than diffraction limited types. The surface is coated with an enhanced 94% reflection layer and a protective quartz layer. The primary mirror has a central marking as an adjustment aid.

Every TS Carbon Newtonian is tested on our optical bench before shipping:
These are a solid telescope for life. After assembly, Each UNC Newtonian is subjected to an optical test at the workshop before shipping. This ensures that the telescope will fit your accessories perfectly and will deliver the optical performance promised.

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

Additional focus positions and change of secondary mirror diameter:

1. The focus position No.1 - with 60mm above the 2" receptacle has proven to be very versatile. Nevertheless, we can also offer you individual focus positions and other secondary mirror sizes - Just contact us prior to purchase.
   
2. Focus position No.2 - 30mm above the 2" connection - optimal for visual observation. The secondary mirror can be slightly smaller, we recommend a secondary mirror with 63mm (minor axis) which is sufficient even for 2" eyepieces.
   
3. Focus position No.3 - 90mm above the 2" connection - this allows you to use a 0.73x reducer/corrector and change the focal ratio from f/6 to f/4.4 (@657mm). The combination is then designed for cameras up to APS-C format. We recommend the secondary mirror with 70mm (minor axis).

Assembly and collimation instructions:
The telescope is delivered disassembled into several units for safety. The assembly and adjustment are not complicated, you can download the instructions in advance. To see what's involved the PDF can be found here.
