Optec TCF-Si Focuser
This TPO focuser package was developed by Optec and includes an adapter to fit to your TPO 10 to 24" RC Telescope and a 12 foot long USB to RJ12 cable for computer control.
Mechanically, the Optec TCF-Si is a robust Crayford style motorized focuser with high repeatability, no play and nearly zero backlash of only 0.0013 inch. Optecs implementation is ideal for applications which require exact focus such as CCD imaging or film astrophotography. A geared stepper motor rotates the drive shaft with one step rotation of the motor equal to a 0.000086 inch movement of the drawtube. Focuser control is accomplished via direct serial connection between the focuser and computer. The TCF-S focuser can easily handle cameras and instrument packages weighing up to 10 pounds. The TCF-S can be used with a PC for automatic focus with some of the popular camera control software.

- Questions & Answers
Product QuestionsIs it possible to make a threaded connection between camera or filter wheel and this focuser or only via a friction fit nosepiece?Question by: Glenn Newell on Jul 17, 2017 4:50:00 PMThis focuser does not have the option for a threaded connection on the camera side - only a slip fit connection. As long as the nosepiece is tapered or safety notched at the top and the three set screws are tightened, this focuser will have no issues with lifting 10 lbs of weight.Answer by: Chris Hendren on Jul 19, 2017 9:50:00 AMThe include items list mentions a 'M117 x 22mm adapter for TPO 10 or 12" RC Telescopes'. Would a different adapter be required for the 16" model?Question by: Richard on Mar 20, 2015 5:10:00 AMYes, The TPO focuser is made by Optec, which uses an ASCOM driver to control the focuser. Sequence generator Pro can use any ASCOM controlled focuser: http://mainsequencesoftware.com/Content/SGPHelp/SequenceGeneratorPro.html?SupportedEquipment.html.Answer by: Chris Hendren (Admin) on Mar 26, 2015 3:52:00 PM
