Description
TS Optics 10" f/5 Imaging Newtonian - improved mechanical system - for deep sky photography and observation
... Aperture: 254mm / focal length: 1250mm / photographic speed: f/5
... Complete package with sturdy Celestron CGEM mount

TS Imaging Newton 10z auf CGEM

The 254/1250mm photo newtonian by TS Optics offers an optimal base for high-resolution astro photography. Its fast f/5 system allows moderate exposure times and the 78mm secondary mirror illuminates even bigger sensors. Of course this telescope is also a recommended choice for those who are more into visual observation.

Advantages of the TS 254/1250 Imaging Newtonian:

-- fast f/5 system for moderate exposure times
-- low secondary obstruction of approx. 30% causing low diffraction effects compared with SC or similar systems
-- free tube diameter of 290mm - no main mirror vignetting and lower tube seeing effects
-- integrated fan for fast temperature stabilization
-- improved MONORAIL focuser - superior to similar Crayford systems - with 1:10 dual speed transmission
-- enough back focus for DSLR cameras and off-axis-guiders
-- clampshells with threads for guiding scopes
-- mirror surfaces with enhanced reflectivity for better quantum efficience
-- precise diffraction-limited optics

Monorail Auszug des TS Imaging Newtons

Astro photography with the TS 254/1250mm Imaging Newtonian:

The OTA's mechanical system and especially the 2" Monorail focuser are designed for high loads and high precision also. For long exposure times, a stiff system is essential.

2" coma corrector by TS:

A fast Newtonian system needs a good coma corrector. The new 2" TS coma corrector is a highly recommended photogrphical accessory part, optimized for such telescope designs. With its bigger aperture, it offers better field illumination than standard T2 systems.

Fast cool-down time and easy collimation:

TS Imaging Newton Lüfter

The TS imaging newtonian is equipped with the proven metal nine-point mirror cell. Collimation is done with three black knurled screws and three counter screws. The relatively free situated main mirror and the 12V fan guarantee quick temperature stablilization.

Improved field illumination:

A manko of many Newtonian systems is a too narrow tube. The free aperture should be approx. 30mm wider than the main mirror diameter. At this telescope, the front baffle has a diameter of 290mm (36mm more than the main mirror) thus guaranteeing a non-vignetted field. This is a circumstance unfortunately forgotten by many competitors.

The German equatorial mount CGEM by Celestron:

This mount can be used for astro photography with telescopes up to approx. 20 kgs. It is a still transporable solution and offers load capacity for accessories like guiding scopes, cameras etc.

Main features, beneath the good stability:

-- Software optimized for astro imaging (easy polar alignment, permanent periodic error correction...)
-- Autoguiding port (ST4)
-- Precise GoTo system with approx. 40'000 objects
-- Precise tracking system with low periodic error
-- Incl. NexRemote PC control software with advanced PEC control
