Looking forward to seeing what you can bring down with that new Mak-Newt of yours, glen. It sure looks like a top instrument and I am surprised there aren't more of them out there and in larger aperture sizes (maybe there are? I couldn't find any, just the Skywatcher offerings.)
Between your Mak-Newt and Greg's Riccardi-Honders, we're all but doomed this winter
