The UNC20012 Newton is checked and adjusted by us before delivery. The focuser is set.

All Newtonian telescopes should be adjusted before first use and then periodically for a clear image. We adjust all of our Newton before they leave our house.

These telescopes are shipped free of charge in Germany.


 

UNC20012 TS Carbon Newton 200mm f / 6 - Planet Telescope - Zero Expansion

TS Optimized Newton with carbon tube and 2 "TS ACUN focuser
... opening 200mm f / 6 - with optimized focus position for minimal shading
... zero expansion main mirror (no expansion due to temperature differences) - ready for immediate use


The UNC Newton Series of Telescope Service offers an alternative to Newton's Far East and the very expensive high-end telescopes. You do not need to compromise on these telescopes. UNC stands for Universal Newtonian telescopes with carbon tube.

- High-quality manufactured in Germany carbon tube with highest stability
- Optimized focus position as desired and thus also the best possible illumination
- From telescope service improved main mirror capture
- ACUN 2 "Crayford Extract with reduction - one of the best Crayford excerpts in its class
- The catch mirror is glued with correct offset from us individually to the secondary mirror (metal)

!!! Each carbon tube is custom made for your UNC Newton.

The UNC20012 is an excellent planetary telescope:

The "Zero Expansion" primary mirror is comparable to the expander features with Zerodur. Even with extreme temperature differences, this material does not change its extent. The optimal mirror surface and thus the image quality are fully preserved. The secondary mirror has a diameter of only 50mm (small axis) and thus causes a shading of only 25%. The diffraction-limited primary mirror and the shading of just 25% make the UNC20012 a real APO alternative for all star friends who enjoy a superb image on the moon and planets.

The technical data of the UNC20010:

Free opening: 200mm
Focal Length: 1200mm
Opening ratio: 1: 6
Main mirror: Mirror carrier Zero Expansion - Diffraction limited image - 94% reflection
Mirrormirrors: 50mm diameter small axis - 94% reflection
Tube: Carbon - inner diameter 230mm / wall thickness 2.5mm
Reinforcement of the tube by aluminum end pieces
Focuser: 2 "ACUN focuser with 1:10 reduction - with individual base for the tube
Socket: Main mirror holder metal - fully adjustable
Fangspiegelfassung - metal - fully adjustable
Focus position: 80mm above the tube - 30mm working distance from the 2 "sleeve of the focuser - optimal for observation Astrophotography with DSLR is only possible with the TeleVue Paracorr If desired, the focus position 110mm above the tube is possible, which then allows Standard DSLR cameras work, a coma corrector is no longer necessary.
Photographic illumination: 100% illumination D = 20mm (with focus position 80mm over tube) or 15mm with 110mm over tube (suitable for DSLR cameras)
Weight: 7,4kg
Length Depending on the back focus - approx. 1180mm
The 2 "TS ACUN2 Crayford focuser:

A key element of the TS UNC Newton is the modern TS ACUN2 focuser. The extract builds from the tube edge only 50mm and still carries heavy cameras and accessories up to 4kg without tilting.

- high rigidity with extremely short length
- exact 1:10 micro reduction - so succeed in perfectly focused Astroaufnahmen
- Motor focus can be removed - with the TS motor focus Advantage: Manual adjustment possible with attached focuser
- Fastening of accessories possible - the focuser is already supplied with the 65mm connection thread
