TS-PHOTON 154/600mm Advanced Newtonian with Carbon Tube for astrophotography and observing
Astrophotography is easy for you with this compact Newtonian from the TS-PHOTON series. Due to the aperture ratio of f/4, this astrograph provides pure speed and therefore short exposure times. Of course, we also offer the matching coma corrector TS SUPERFLAT. Thus this PHOTON Newtonian becomes a very good astrograph.
With approx. 5 kg weight and only 530 mm length, this Photon Newtonian is an ideal travel telescope. For wide field observations, you can even mount the telescope on a good photo tripod. The dovetail bar provides the matching 1/4" photo thread at its base.
Of course, the rich field Newtonian is best placed on a good astronomical mount, for example the EQ3-2 from Skywatcher or a good GoTo mount. Then there is nothing more to prevent a fulfilled astronomical viewing session.
The advantages of the carbon composite tube:
The TS-PHOTON Newtonian comes with a high-quality carbon composite tube. Beside the weight advantage of approximately 0.5 kg, the main advantage is the better stability of the focus when the temperature changes. That is imortant for astrophotography. Then the temperature falls, metal contracts and the focus moves. Readjusting the sharpness becomes necessary. This combination of tube and mirror makes readjusting the sharpness usually obsolete even for long-term exposures. The images become sharper.
Berger Anti Reflex Paint for best possible internal blackening:
For this PHOTON Newtonian, we use Berger Antireflexfarbe (anti-reflex paint). It darkens the inside of the tube as well as velours foil. The big advantage, besides a lower weight, is that the paint almost gathers no dust. The optics stay clean. With velours foil, dust gathers at the primary mirror very quickly.
The image at left shows the difference between Antireflexfarbe and standard solutions. The diagram above shows a direct comparison between standard school board paint and Berger anti-reflex paint.
