Scorpius/Sagittarius widefield (done "properly"!)

Hi All,

Having just learnt how to drive Deep Sky Stacker a couple of days ago (when stacking images of an ISS pass), I decided to try and do a "proper" widefield shot of the galactic centre.

For this image I used 25 x 8 second exposures taken with a tripod-mounted Pentax K100D and 50mm f/1.4 lens set at f/2.0 and 800 iso. I also did 20 darks. After stacking in DSS, I adjusted levels, curves, red channel and contrast in PS7. These PS adjustments were rather random, I just played around until I thought the image looked OK. The end result is nothing too spectacular compared to most of the images posted on this forum, but I guess you have to start somewhere, and I'm happy to have picked up 13 Messier objects from what was a very light polluted sky! Looking forward to repeating this from a dark sky when I get the chance...

Any comments or advice will be greatfully received!

Cheers,
Stephen
