M1 - Crab Nebula
 
I was feeling like experimenting and on 3/19/2010.  I wanted to try M1 (Crab Nebula).  It was right on the West from where I'm, which it is pretty much pointing over the Portland lights.  My West and South skies get the heaviest LP, and I only went for a 30 min. exposure which it is not enough for this faint nebula, but I still got some detail.
 
Processing of this object with such a little exposure and heavy LP was tough, but I was able to pull a little bit of detail.  It won't definetely be my proud award inspiring picture, but it was a good experiment.
 
Mount - HEQ5 Pro (AKa Sirius)
Camera - Canon 40Dh
Guiding - ST80+PHD
15 subs x 2 min. = 30 min. total exposure
40 darks + 43 flats + 40 bias
Exterior Temp. 54 degrees
Chip Temp. 58 degrees approx.
 
RA: 05h34m29.73s
DEC: +22deg.00'48.3"
 
Processing: I was not able to find a G star on this picture, so I used eXcalibrator for color balancing, although, it was tough due to the heavy LP.  I used DSS Mediam-Sigma clipping for stacking processing.  Photoshop CS4 + Carboni + GradientXTerminator.
