I've done this one before, but wasn't particularly pleased with it due to some dust spots for which I didn't have a flat field to correct. I'm much more pleased with this one... my tracking was very accurate and I got a relatively large set of exposures to combine. I also ran SGBNR on it. I still haven't mastered all the knobs and doohicks on SGNBR, but it does do a great job of noise reduction.
