This telescope is a true all-rounder and ranks among the best in this range. Through the versatile focal ratio of f/5, the Newtonian offers best prerequisites for lunar and planetary observations. The optimized secondary mirror is designed for deep-sky observations as well as for astrophotography.
Why do we recommend a PHOTON Newtonian instead of all other comparable Newtonians?
We offer this Newtonian telescope with a 2" Crayford style focuser with integrated 1:10 dual speed transmission. This focuser works very precise even with heavy accessories like astro cameras. With a bit of experience, you can achieve accuracies around 0.08 mm which is sufficient even for very high resolution sensors.
The focuser is fully compatible with the optional TS Motorfocus system, allowing vibration free and precise focusing for visual observing or astro-imaging.
This Newtonian shows its full potential at observation and astrophotography due to a high-quality primary mirror made of optical BK7 glass, free from internal stress. The parabolic mirror has a 94% reflectivity coating, thus offering a brighter and contrastier image. You can instantaneously notice the difference to a standard coating.
Due to the focal ratio of f/5, this Newtonian belongs to the all-round telescopes for astrophotography and observing.
No shadow at the edge, you will be satisfied with a bright image with full illumination even with modern DSLR or CCD cameras. But 2" wide field eypeces are also supplied with light up to the edge of the field stop.
Only a good coma corrector turns this Newtonian into a true astrograph. Our recommendation is the TSGPU corrector which is ideal for this telescope. It will provide maximum sharpness in the entire field, so only the TSGPU (see accessory recommendations) makes a true astrograph out of this Newtonian.
Astrophotography with DSLR cameras:
♦ TSGPU Coma Corrector
♦ use a T-ring to the camera mount
... and you already have the optimal distance and get sharp stars in the entire field of view. Guiding can be done via the finder or a small guiding scope which fits into the finder shoe (or bracket).
