SBIG CFW10 10-Position Filter Wheel for the ST-7, 8, 9, 10 & 2000 USB Model Cameras, Filters Not Included. Reviews
The SBIG CFW10 is a ten-position filter wheel designed for the USB version of the ST camera series where a serial port is available for controlling the wheel. The CFW10 accepts control input via the I2C port. When attached to an ST-7/8/9/10/2000 USB camera, the filter wheel receives power and control commands through the I2C accessory port of the camera - no additional power or cable to the computer is required. The portion of the housing between the camera and the telescope is only about 3/4" (20mm) thick for minimum back focus. Two versions of the housing make it possible to use the CFW10 either as a separate unit, or as an integral piece replacing the face plate of the ST series camera. The replacement version contains a high quality optical window with superior AR coatings. By using the filter wheel housing as a replacement face plate for the camera, an additional 1/4" (6mm) in back focus is eliminated. The front aperture of the CFW10 contains standard t-threads. A custom camera lens adapter will be available for commonly available 35mm Nikon, Canon, Olympus and other lenses. For attachment to the telescope, a 1.25" nosepiece or 2" nosepiece may be used, or a t-thread to visual back adapter for more secure fit to Schmidt-Cassegrain scopes. For other scopes, any adapter with male t-threads can be used to secure the filter wheel.
