TS-PHOTON 154/600mm Advanced Newtonian for Astrophotography and Observing

Astrophotography is easy with this compact Newtonian from the TS-PHOTON series. With an aperture ratio of 1:4, this astrograph offers you pure light intensity and thus short exposure times.With the addition of a coma corrector the PHOTON f/4 Newtonian becomes a fast high quality astrograph. 

With a weight of around 5kg and a length of only 53cm, the PHOTON f/4 Newtonian is an ideal travel telescope. For wide-field observations, you can even mount the telescope on a good photo tripod - the included dovetail has a 1/4 "tripod thread on its base.

A good coma corrector turns this Newtonian into a real astrograph, our recommendation is the TSGPU Superflat corrector, which is made for this telescope. It will offer you the highest sharpness in the entire field.

The PHOTON 6" f/4 is also suitable for the TS2KORRR reducer / corrector. The corrector turns the already bright f/4 Newtonian into a fast astrograph with an aperture ratio of f/2.9. The exposure time is reduced by about half. Sensors up to 30 mm in diameter can be used.


  • Aperture 154 mm (6") - focal length 600 mm - focal ratio F4
  • High-quality parabolic primary mirror with enhanced reflectivity for a brighter image.
  • Large secondary mirror for a well-illuminated image with astro and DSLR cameras.
  • Precise 2" MONORAIL focuser for more stability than with conventional Crayford focusers.
  • Adjustable primary and secondary mirror cells made of metal, useful collimation aid on the primary mirror.
  • With only 530 mm length and approx. 5 kg weight, this is an optimal travel telescope which can even be mounted on good photo tripods.
  • Focus position ready for the TS GPU Superflat Corrector and the TS 2KORRR 0.73x Reducer / Corrector.
  • Central mark on the primary mirror for easy collimation
  • Extensive scope of delivery: 8x50 finder, tube rings, 2" extension tube, adapter to 1.25"
  • Weighs 5.3kg including tube rings and finder.
  • 540mm long with a 178mm diameter.

Dazzling reflectivity!
Monday, 20 September 2021  | 

From Gary in Derbyshire
I had received my TS Photon 154mm f4 promptly and all in excellent condition, but hadnít had the opportunity to use it all until early this morning. Shortly after I had woken up, at 04.30 hours, I was greeted by a clear sky, not what I had expected, as we had experienced almost a month of overcast skies. However, this morning the waxing almost full moon was beginning to set over the hills opposite me. To start I simply put a 26mm Meade Super Plossl eyepiece into the eyepiece holder and enjoyed the view; I then replaced it with an ED 12mm Starguider eyepiece. Not having consulted my star chart app for a few days, and certainly not expecting to do any observing at this hour of the day. So, I was somewhat astonished to find myself looking at a planet! It was a cool, silvery blue - and it was Neptune, a tiny pinhead beauty.. I have to say that I am very pleased with the oversized primary mirror of this telescope, it dazzles with high reflectivity.. I would also like to thank FLO for their usual fast, professional service.
