Folks,
First post of a fuzzy image here, so please be gentle
Southern Cross, the Coalsack, eta Carina and the Southern Pleiades from a single 10s exposure using a Canon 1100D and Canon 50mm f/1.8 lens, ISO1600, on el cheapo tripod so there's a little trailing on the full size.
Question: I took 20 of these, all pretty much the same (besides the rotation of course), and when I try stacking these in DSS (with darks and bias) I seem to loose all the lovely colour information that I see hints of here

any ideas what I'm goofing up?
Cheers,
Dunk
