Why we recommend a Newtonian from the Photon series before all other comparable Newtonians:
The primary mirrors of the Photon series are from GSO. Since years the manufacturer manages to keep the optical level of the mirrors evenly high. The Photon Newtonian telescopes are built according to the specifications of Teleskop-Service. The secondary mirror size is optimized, the distances for the focus position are also optimized for observation and photography. But above all, Photon Newtons can adapt to your interests, they can "grow with you":
♦ We offer a carbon tube kit for each Photon 10" Newtonian, where you can reuse all parts of your Newtonian.
♦ We offer smaller or larger secondary mirrors, so you can adapt the Newtonian to your individual interests, no matter if you want to observe planets or take pictures with a full frame sensor.
Astrophotography with the ZWO cooled cameras
The cameras from ZWO and the fast Newtonian with the TS Maxfield corrector are an optimal team for astrophotography. The stars are sharp to the edge. The adaptation from the corrector to the camera is easy, we will be happy to advise you.
The advantage - already after 40 seconds you have galaxies, nebulae and star clusters on the sensor. Longer exposure times are not necessary, a guiding control is not necessary. Just let the well polar-aligned mount run and wonderful astrophotographs will be taken almost by themselves. The high f/5 speed of the Newtonian and the extremely fast sensor of the camera make it possible.
