Description: Reprocessed version of NGC 3642. I wasn't very happy with the first image; I got a little aggressive with trying to pull the galaxy's details out of the image. I finally came to the realization that the galaxy is just very faint and I tried to get a more natural image without over-processing the image.

Description: Bottom line: The first two iterations of this were terrible. So I decided to try the data again. The result is much, much better but I also realized long the way that I had never incorporated drizzle data into the image, so that will be coming soon. Additionally, something must have been amiss with my dither setting for this capture. There was some crazy noise that I had to fight with which I normally don't see with this camera...who knows.
