GSO 8" f/8 RITCHEY-CHRETIEN & ESATTO 2"

The Guan Sheng Optical (GSO) 8" f/8 Carbon Ritchey-Chrétien is an excellent telescope for deep sky astrophotography. This bundle includes the Prima Luce Lab ESATTO 2", a highly accurate robotic microfocuser with a weight capacity of 5kg an incredible resolution of 0.04 microns per step.

Note: you will need to purchase an additional camera adapter for the ESATTO 2" to suit your equipment. Esatto is shipped in its original packaging and does not come pre-assembled to the scope.

GSO Ritchey-Chretien 203mm f/8 with carbon fiber tube and ESATTO 2" and the following optional accessories: EAGLE with PLUS dovetail clamp installed above the telescope, ECCO environmental module.

While Prima Luce Lab's Esatto upgrade kits are engineered to the exact specifications of the telescope. If the manufacturer changes the design of the tube or the manufacturing tolerances are too great, this is out of our control. As a result, this could put the focus point outside of the range of the Esatto. If this is the case, we have plenty of different extensions available and can design custom adapters if necessary.

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 quartz 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 carbon fibre tube and features computer-optimized baffles to eliminate stray light.
