Description

TS-PHOTON 154/600mm Advanced Newtonian 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 GPU SUPERFLAT and the very interesting 0.73x Reducer Corrector TS2KORRR. 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, we recommend an EQ3 or better with GoTo drive. Then there is nothing more to prevent a fulfilled astronomical viewing session.
