GSO OTA & FOCUSER BUNDLES
Guan Sheng Optical Ritchey-Chrétien telescopes are exceptional long focal length imaging machines, but to really make the most of them an electronic focuser is needed.
The Prima Luce Lab ESATTO and SESTO SENSO are the perfect companion to these monster tubes, with sub-micron accuracy and huge weight capacity (up to 8kg for the ESATTO 3")!
