Product description

GSO RC astrograph:

This is a newly developed telescope from GSO, for the first time at a more affordable price, and is especially suitable for astrophotography as it is a pure reflection system and so has no chromatic aberration. This is due to the use of two mirrors - a hyperbolic primary mirror and a convex hyperbolic secondary mirror. The image is coma-free and has a wide field of view. The open system and quartz mirror mean that RC OTAs cool quickly and there is virtually no problem with dew. This ingenious system even allows infrared photography.

The advantages in a nutshell:

  • ideal for astrophotography
  • no chromatic aberration
  • open system

Great satisfaction .
This is one of the fast with TS Optics 2'' CCD reduction, 0.67X for RC, quality and precisely made binoculars. Focusing the binoculars for the photo needs to be bought separately, this is one of the minuses of the asterisk. I recommend TS-Optics 2 inch rack and pinion focuser with additional thread for accessories up to 5 kg. Photos from said telescope here:
