I have a set of 0.33 & 0.5X Optec WideField telecompressors that will not work with my new camera/filter wheel setup so I'd like to sell them to help finance the purchase of a new telecompressor that will work. A mounting bracket for use with SBIG ST cameras is included. Price is negotiable. Please reply to paw@wirelessbeehive.com if interested. Cheers, patrick
