Parallel cable and regulated power supply for controlling a SBIG CFW-8a filter wheel directly through the parallel port. Requires MaxIm DL/CCD software. This cable and supply allows you to use a CFW-8a filter wheel with any camera supported by MaxIm DL/CCD such as those made by Starlight Xpress. My price is $30.00 and includes FedEx Ground shipping to the CONUS. CFW-8a and MaxIm DL/CCD are not included. Thanks for looking.
