AutoGuider Focusers

Reduce autoguider focusing time to seconds!

STI Autoguider Focusers are available for  dedicated autoguiders  such as the SBIG ST-4 , the SBIG STV, the Orion StarShoot, the Meade 201, LPI, and DSI-C models, and for the Starlight Xpress model. These autoguider focusers effectively use a 180 line/inch ronchi grating for focusing.  If you already own a Series IV focuser, you may easily convert any of our autoguider focusers into a regular Stiletto camera mount with the addition of a converter ring listed below.
