I wonder if we should have a thread specifically for the techniques of astrophotography? Where people can talk about their equipment, strategies for image calibration, software and tutorials.
We do that at Dpreview. I have been pimping this site like crazy on there, including posting screenshots
I hope I've gotten a few people to download the software and join lol.
Two things I'm extremely interested in are astronomy and weather. So I typically run SE, Stellarium and Yowindow all the same time. I'm also a numbers and records buff so I have something like 250 locations saved on Yowindow (hottest, coldest, snowiest, rainiest, driest, most remote, furthest north, furthest south- in each hemisphere.)
