The GSO 2" MR&P-RC focuser with rotator is a precise and robust optical element designed for Ritchey-Chrétien telescopes and other designs requiring high load-bearing capacity and focusing accuracy. The rack & pinion mechanism ensures smooth and stable focusing, even with heavy astrophotography setups.

The focuser is equipped with a rotator that allows for 360° rotation, which allows for easy framing of the image without having to change the equipment configuration. The M90x1 thread allows for direct mounting to GSO RC 6"-8" telescopes and other compatible structures. On the other hand, the focuser offers 2" and 1.25" adapters, which ensures wide compatibility with photographic and visual accessories.

With a load capacity of up to 4 kg, this extension is perfect for advanced astrophotography, providing stability and precision even with heavy cameras and filter wheels. The possibility of mounting a focusing motor (e.g. ZWO EAF) additionally increases the functionality of the set.
