New in box never used Televue photo flattener for refractors of 480-700mm focal length (TRF-2008). Works with TV 85 and Pronto. Wonderful for flat field images with 35mm camera or for expanding your field of view for CCD imaging. I am using the TV101 with the flattener for the TV102 for imaging and do not need this flattener. I don't think I have even had it out of the box. Shipping included in US.
