The TCF-S temperature compensating focuser from Optec is a very sturdy and precise focuser. The adapters I have will make it fit a SCT back, but it will fit basically any OTA (with the correct adapter). The focuser itself will fit some refractors without any adapter.
The package consist of the following items:
-
TCF-S focuser: Sells for 5100SEK (795USD) at Optcorp.
-
Cables: Power cable, cable to connect the focuser with the control box, cable to connect the control box to the PC.
-
Temperature sensor:
-
Adapters: Adapter to attach the focuser to a SCT (2"). Three adapters on the camera side; 2" to 1.25" adapter, 2" to SCT adapter, and a 2" to T-thread adapter. They sell for 290SEK (45USD) a piece at Optcorp.
The above sells new for 5900SEK. I will sell for 2500SEK or included in a larger package.
