About this product

This William Optics 3.3" Rack & Pinion RC Focuser is compatible with GSO/Stella Lyra Ritchey-Chrétien 10"/12"/16"telescopes.
Adding this RC dual speed focuser to your RC telescope will help you achieve superior focussing during your astrophotography sessions by using the rough and fine focus knobs and offers better load bearing capacity and stability when compared to the standard GSO focuser

The telescope side of the focuser uses a large flange to connect the focuser to the OTA. The flange also acts as a spacer, providing more space if you would like to add a user supplied filter wheel and/or Off-Axis Guider (OAG).
