Hi, just stumbled across the Astrophotography group and your pictures. Just blown away by your Andromeda image. I know nothing about stacking but did indulge in quite a bit of film-based shots of moon, sun, constellations etc. My enthusiasm to test out my Kr has been spiked. I'll sign up to the group, but probably won't have any pictures posted until after Xmas - have a wedding to help organise for one of my children and a few other demands on my time.
