Just saw the info in S&T on this. Does anyone have further info on it? Anyone take the leap yet or too soon? I would assume it would kill the warranty on my PST. Not sure that would matter too much with the stories about current Meade repair service quality. Denk is a reputable company and would not seem there is too much risk. For another $600 investment you get the added aperture, 600mm focal length, upgraded focuser knob, and an enlarged block filter. The picture of it does show an almost Galilean looking scope with this very long, slender tube.
