TS-PHOTON 12" F5 Advanced Newtonian Telescope with Carbon Tube

TS-PHOTON 305/1500mm Newtonian Telescope with Carbon Tube - OTA

This telescope from the PHOTON series is a real all-rounder and is one of the most powerful telescopes in this price range. Due to the versatile focal ratio of f/5, the Newtonian offers best conditions for lunar and planetary observations. The optimized secondary with 80 mm diameter (small axis) is also designed for deep sky observations and astrophotography. The obscuration of only 26% and the extremely accurate primary mirror allow magnifications up to about 750x, with a suitable air quietness. The limit of resolution is practically only the calmness of the earth´s atmosphere, the seeing.

The 12" f/5 PHOTON Newton requires a stronger mount, like the EQ8 from Skywatcher or the CGX from Celestron. With the CGX, the Newtonian is even more portable, taking into account the tube length of 1400 mm. But mainly the 12" Photon Newton is a telescope for the fixed installation in the garden or in an observatory.

We recommend the TS-PHOTON 305mm f/5 mm to all star enthusiasts looking for a versatile telescope for astrophotography and deep sky observing.

The advantages of the carbon tube:

The TS-PHOTON Newtonian comes with a high quality carbon tube. Besides the weight advantage of about 3 kilograms, the main advantage is the better stability of the focus during temperature changes. This is important for astrophotography. When temperatures drop, metal contracts and the focus moves. A readjustment of the focus is necessary. The combination of tube and mirror makes it hardly necessary to readjust the focus, even with long exposures. The images become sharper.

TS antireflective paint for best possible internal blackening:

TS antireflective paint is used for this PHOTON Newton. It darkens the tube interior just as well as velour film. The big advantage besides a lower weight is that the paint hardly collects dust. The optics remain clean. With velor film, dust accumulates very quickly on the main mirror.

The figure on the left shows how dark the anti-reflective paint is. The diagram (figure above) shows the direct comparison of school varnish / TS anti-reflective paint.

General info and features of TS-PHOTON Newtonian telescopes:

Fast parabolic optics with excellent contrast and very good sharpness for planetary observing.

High quality 2" monorail focuser with 1:10 micro reduction for 2" and 1.25" accessories.

Focal point position ideal for DSLR and other cameras.

All common 1.25" and 2" eyepieces can be used without problems.

Brighter image due to forced 94% mirroring on main and secondary mirror.

Motorized focus can be retrofitted at any time.

A 0.5 mm thin stainless steel secondary spider ensures stability. Astrophotographers will envy you for the razor-sharp spikes around bright stars.

Active main mirror ventilation provides much faster cooling.

Adjustable main mirror mount and secondary mirror mount made entirely of metal.

More joy in astrophotography by optimal field correction

Only a good coma corrector makes this Newtonian a real astrograph. Our recommendation is the TSGPU corrector, which is made for this telescope. It will give you highest sharpness in the entire field, only with the TSGPU (see accessory recommendations) this Newtonian becomes a real astrograph.

The working distance from the M48 thread is 55 mm. With a T-ring you are automatically at the right distance for astrophotography with DSLR cameras. Suitable adaptations for your astro camera can be offered at any time as part of our service.
