Works In Progress

Both could use a lot more light. First we have the veil nebula, followed by the butterfly nebula.

M33, 1 hour 45 min

This is 1 hour and 45 minutes of M33 taken with the Sky 90 at f/4.5 with an st-2000 and SBIG clear filter. Flat and dark reduced and stacked in CCDSoft, further processing in Photoshop. Subframes were 5 minutes each.


Is this gradient (lower left to upper right) typical for light pollution in a widefield image shot in moderate light pollution, or is there something else at work here??? Frames are flat and dark subtracted.

Deer Lick/Quintet and more, 3 hours

This is 3 hours of The Deer Lick Group, Stephen's Quintet, and other misc friends. Could have gone a little longer but was getting the itch to catch some light on M33, see above. Same setup and processing as usual, shot through SBIG clear filter. 5 min subs.

Cocoon


Another Hydrogen alpha image. Probably would have been better if I just shot throught the clear filer, but the moon was only a couple days past full. Oh well, maybe next time.
