We’re delighted to announce the release of the Hitec FocusMaster Deluxe, a high quality digital focus controller for stepper motor based focusers. FocusMaster includes inbuilt temperature compensation. An external temperature sensing probe is included. Also included is comprehensive operating software, and ASCOM 6 compliant driver and full documentation. All of this is available for download from our support area. We have extensively tested the autofocus ability of this unit and find that FocusMaster is capable of autofocusing even an F/11 14″ SCT right to the limit of the seeing conditions (using free FocusMax software). We are very excited about this product and we hope you will be too. So why not download the documentation grab some coffee and have a read we think you see why we’re so excited about this arrival from Hitecastro.
