TS-Photon 250 mm f/4 Advanced Newtonian with carbon tube

The powerful Newtonian with carbon tube is optimized for astrophotography and offers very good speed for short exposure times thanks to the focal ratio of f/4. The generous back focus allows the connection of suitable coma correctors for very good field correction. We particularly recommend the TS GPU "Superflat" corrector. This turns the 10" Photon into a very good astrograph. Of course, the Photon is also suitable for observing.

The advantages of the 10" TS Photon Newtonian:

Fast, high-quality parabolic primary mirror for very good contrast and sharpness

Improved 3" rack-and-pinion focuser - with M77x0.75 female thread and M74x0.75 male thread for screw adaptations

Massive secondary mirror spider struts, twisting is no longer possible, which facilitates collimation (Gen. 2)

Generous working distance from the 2" receptacle of the focuser, so that all common correctors can be used

Brighter image due to enhanced mirror coating on primary and secondary mirror

Primary mirror cell and secondary mirror cell are adjustable and of course made of metal

Astrophotography with the TS-Photon 10" f/4 Newtonian:
Only a good coma corrector turns the Newtonian into a real astrograph. Our recommendation is the TSGPU "Superflat" corrector, which is perfect for this telescope. It will offer you a very high sharpness in the entire field. The illumination is very good up to APS-C format. Correction is even given up to full-frame format. Of course, we always recommend a FLAT for even brightness distribution. Suitable flat field generators are of course available from us. The working distance from the M48 thread of the GPU is 55 mm, making it suitable for all common cameras.
