The Coronado DS40 has taken a bit of a comeback: I have replaced the objective lens that was astigmatic with one that appears to be fine. The external etalons have been aligned with respect to each other and all has been mounted back on the original coronado tube assembly. While the focuser still needs some work to improve things it is at least now a usable scope. This should work well in winter months when the low altitude sun and poor seeing are a major consideration. The double stack image is really nice! I just wish I had one in more aperture!
