I'm selling my Optec focuser becuase I moved up to a rotator focuser. The focuser works great, all the cables are included to get you started. The telescope side of the focuser has the adapter to thread onto a SCT with a 2 inch thread ... a Celeston telescope. The backlash is extremely consistent at 50 steps and the temperature regualtion works great once setup. The TCF-S can handle camera and instrument packages weighing up to 10 pounds! It connects seamlessly via ASCOM to NINA or SGP. The price is low because I have had it for a long time, but it has lived its entire life in a climate controled observatory. 

Continental US sales only 

Thanks for looking
Walter
