Ritchey-Chrétien


 

The Guan Sheng Optical (GSO) 6" f/9 Ritchey-Chrétien is an excellent telescope for deep sky astrophotography of galaxies and planetary nebulae. This bundle includes the Prima Luce Lab SESTO SENSO 2, a highly accurate robotic focus motor with an incredible resolution of 0.7 microns per step.

 

 

GSO Ritchey-Chretien 152mm f/9 with SESTO SENSO 2and the following optional accessories: EAGLE with PLUS dovetail clamp and guide scope installed above the telescope, ECCO environmental module.

 

The Guan Sheng Optical RC's are excellent astrographs with solid build quality and precisely-figured optical surfaces. The concave hyperbolic primary and convex secondary mirrors deliver excellent correction across the field. The low thermal expansion BK7 mirrors have a surface correction of 1/12th Lambda PV or better and have highly reflective dielectric coatings ensuring 99% reflectivity.

The telescope is made with a rigid steel tube and features computer-optimized baffles to eliminate stray light.
