UNE VITESSE POUR RÉFRACTEUR (ROUGE) / SINGLE-RATE FOR REFRACTOR (RED)
The CF model focuser has a 2" ID format drawtube with up to 4.5" of travel and comes with a 2" to 1 1/4" adapter that is threaded for filters. We offer this model in both a single rate configuration and our popular dual rate 8 to 1 Tri-knob reduction unit for heavy load (CCD imagers and bino viewers). We added a new shaft lock system to the left knob allowing the focusers position to be locked using a micro compression ring clamp on the left knob. This type of lock does not push against the draw tube like other lock systems do. There is no image shift with this new style of shaft lock system. The focuser also comes with 4 different motor options. A DC motor version with hand controller for visual use or our popular "High Res stepper motor options" for extreme imaging needs requiring very fine repeatability and temp compensation using any ASCOM soft ware. We offer 5 different drawtube styles with travels ranging from 2.5" to 4.5". and many flange sizes allowing the focuser to fit most of today's refractors. We also machine custom flanges by request for any size refractor. All of our new 2-part flanges provide collimatable flexibility for achieving perfect mechanical centerline collimation using our 3 point push /pull mounting configuration. The 2- part rotatable flange design provides camera angle adjustment. Twin dove tail finder brackets are offered on most flanges. Add custom anodized color options and custom machining (by request) for a perfect, one of a kind focuser to match your refractor.
