#17646 - Pyxis T-thread camera mount. Most CCD cameras used in astronomy use this type of threaded mount. This adapter allows use of the NextGEN (0.33X and 0.50X only) reducers to work with most SBIG cameras without the CFW wheel. However, SBIG cameras using the CFW wheel must also purchase the #17654 extender tube. This moves the camera further back so that the CFW motor does not interfere with the Pyxis.
The OPTEC-2400 circular dovetail mount is used for the TCF-S focuser and IFW filter wheel to allow easy connections from most any telescope. If your scope or accessory is not listed, do not hesitate to call. These adapters are required to fit the TCF-S and IFW 2-inch models to various telescopes. One end has the necessary fittings for the particular telescope and the other has a protruding ring with dovetail groove. The three #8-32 setscrews in the TCF-S or IFW clamp down on this ring. Adapters are also compatible with the TCF-S. Most mounts are made from high strength 6061 aluminum alloy and black anodized.
