CCD project - 2001 October 20, with Kevin O'Neill

Kevin and I met at Savage on a beautiful evening that was clear, but with a fair amount of high moisture that limited transparency a bit. We mostly revisited some old favorites. Kevin had to leave early to attend to family matters, but I stayed and tried out a new technique for making "pretty pictures". At least, it was new for me. The technique involves combining stacked images AFTER they have been flat fielded, as opposed to stacking the images before applying a single flat field image. The change is related to my recent acquisition of CCDSoft camera control software, which replaces CCDOps. I was surprised at how much less noisy the final images were.

I also spent quite a bit of time hunting down asteroid 27234 1999 RC2. I managed to capture this mag 17.8 asteroid traveling through Lyra. If I can figure out how to animate the images, I'll post them here so you can see a rock fly.
