TS-Optics GSO Photon 6" F6 Advanced Newtonian Telescope with Metal Tube

TS-PHOTON 150/900 mm Advanced Newtonian for Observation

This Newtonian reflector telescope of the TS-PHOTON series provides much light and features which you will hardly find in this price class. 150 mm aperture already show thousands of deep-sky objects with many details. Resolve globular clusters into single stars or view details of the well-known nebulae. Thanks to the high-quality of the parabolic primary mirror, the Newtonian also shows many detail on moon and planets. With the optional 2" extension TSV235, you can focus all eyepieces easily (see recommended accessories).

There are many Newtonian telescopes for astrophotography, but this telescope is optimised for observation.

Almost any Newtonian comes with a focus position which is optimized for astrophotography. Often the result is insufficient illumination due to too small a secondary mirror (or too much obstruction due to to a too large one) and an unnecessary large focus distance. The 150 mm f/6 Newtonian provides sufficient working distance for all eyepieces, even the ones with an extreme focus position. Eyepieces with a field stop at a very low position should be pulled out of the focuser a little bit for focusing. Alternatively, an extension tube (TSV235) can be used.

Together with GSO, TS has created a Newtonian which provides best results for the visual observer. The secondary mirror has 45 mm minor axis which results in very high contrast and sharpness for moon and planets. The image matches the typical one of an excellent 4.5" apochromatic refractor and at least the one of a very good 105 mm apochromat. The image is even brighter.

With a focus position approximately 50 mm above the 2" receptacle, almost any common eyepiece can easily be focused, the illumination allows even using 2" eyepiece with full brightness over the entire field. By the way: due to an aperture ratio of 1:6, Plössl eyepieces can be used. Their low number of optical elements results in less stray light.

This instrument comes very close to the visual 6" Newtonian which is asked for in several astronomy forums - finally!

The 2" Crayford focuser

More simple telecopes have a 1.25" focuser - sometimes not even made of metal. Of course, this 2" focuser is made of metal. The drawtube is mounted on ball bearings. Even heavy cameras and eyepieces are held without effort, sensitive focusing is possible. The focuser is supplied with a reduction adapter for 1.25" barrels. 2" and 1.25" accessories are locked gently and safe by compression rings.

A superb beginner´s telescope

Thanks to its convenient handling and its solid build, this PHOTON Newton is ideally suited for beginners. For this Newton telescope we recommend the Skywatcher mount EQ3 or EQ5. You find both mounts in our accessory section below. From the outset you achieve wonderful observations of moon and planets, but also of Nebulae and galaxies with this telescope.

[{General information and features of
TS-PHOTON Newtonian telescopes:}]
♦ Light-gathering parabolic optics with outstanding contrast and very good sharpness for planetary observation
♦ High-quality 2" Crayford focuser for 2" and 1.25" accessories - dual speed is optionally available
♦ Focal plane position ideal for DSLR and other cameras
♦ All popular 1.25" and 2" eyepieces can be used without problems.
♦ Brighter image due to 94%-reflection coating on primary and secondary mirror.
♦ Motorfocus can be upgraded at all times.
♦ A 0.5 mm thin secondary mirror spider made of stainless steel provides stability. Astrophotographers will envy you for your sharp stars and needle-fine spikes.
♦ Adjustable primary mirror holder and secondary mirror holder completely made of metal.

But what if you want to start in astrophotography, though?

Taking images of moon and planets is no problem using eyepiece projection or a Barlow lens. But if you want a coma corrector and perhaps a DSLR for deep sky imaging, there is a possibility:

♦ TSGPU - this corrector puts the focus position about 20mm further out, so you can easily focus with all common cameras (DSLR, system or astro cameras).

♦ TeleVue Coma Corrector VIP-2010 - this corrector has the effect of a Barlow lens, it extends the focal length by 15% and brings the focal plane further outward. With this, you take images with all common DSLR and CCD cameras again, too.

Hello! Acquired this telescope TS-Photon 6F6 in March 2021. Over 5 months, he conducted more than 15 field observations with this tool. The quality of the mechanics of optics is very high. With good seeing, it is possible to separate the binary stars Pi Aquilae 1.4". For planets, quality is better than in a 102mm APO refractor. With good seeing of details on the planets (Jupiter), more is visible. Galaxies and nebulae are significantly larger than in the refractor 102mm. When using a UHC filter, nebulae M8, M16, M17, M20, S33, S34, S20 are clearly visible. Star permeability is on the order of 10.5 stellar magnitude. The telescope is very pleased, I recommend for acquisition!

Question:
What is the function of the six screws behind the primary mirror

Answer from Teleskop-Service:
The six screws are for the adjustment (collimation) of the primary mirror. The small screws with the slit fix the position. With the bigger screws you can adjust the collimation. And this is how it works:

♦ Loosen the screws with the slit.
♦ Adjust the primary mirror with the adjustment laser using the bigger screws (with internal thread).
♦ When the desired result is achieved, tighten the screws with the slit minimally. A light pressure is sufficient.
