I have no financial interest in Coulter either, however you forgot to mention that they also make 17.5-inch and 29-inch models. These are really big, and although I've never used one myself I've been told that they are really good for deep-sky objects not requiring much magnification (with respect to the aperture, that is -- the classic problem with an RFT). Check out 'Sky & Telescope' or 'Astronomy' magazines for an ad and address. (I certainly wish *I* had one!!!!)
