Not in stock

Price includes VAT, plus delivery

The Gemini Integra 85 is an exceptional motorised focuser offering ultra fine focusing in 0.05 micron steps. To add to its versatility it also has motorised rotation making it an ideal focuser for use in remote systems. It is arguabley the best value precision focuser on the market today.

The Integra is very compact and only occupies 69mm of back focus. It is controlled and powered by the supplied Gemini controller which is fully ASCOM compatible. This controller will automatically calibrate the focuser on power up.

Also supplied with the Integra are custom front and back plate adapters to allow fitting to your telescope and camera. Please specify your requirements at the time of ordering. The telescope side of the focuser is also fully collimatable to ensure perfect alignment with your telescope.

With its relativley light weight of only 2.3kg, the Integra does not add significant load to your mount or existing tube assembley. We recommend this focuser as a particularly good upgrade for the GSO Ritchey Chretien Telescopes. Obviously they are equally well suited to any of the Telescopes we offer.
