This telecompressor is for use with SCTs and other long focal length designs. Includes telecompressor lens assembly (fits into 2" slip-fit visual back), male T-thread camera mount, 2" violet light rejection filter. Threaded for 2" filters.
External condition is excellent, with light set-screw marks on barrel. Optical condition perfect.
List price is $285 with T-thread camera adapter. I am asking $240 + shipping.
