Louisiana astrophotographer Mike Broussard took this image of Comet Hartley 2 passing NGC 281, the PacMan
Nebula in Cassiopeia, on October 2nd. He used a Tele Vue 85-mm refractor with a Hutech-modified Canon XS
camera and an IDAS-LPS filter. This is a stack of 44 1-minute exposures, 34 2-minute exposures, and 106
3-minute exposures, all at ISO 1600. For processing, he writes, he used "IRIS for stacking, stretching
and initial color balance, and Photoshop with Noel Carboni's Astronomy Tools Neat Image for the final
image." Image and caption from Sky and Telescope Magazine online, fair use for educational purposes.
