Abell 2151 Galaxy Cluster in Hercules - Posted June 7, 2006
For some reason I seem to be gravitating toward galaxy groups this season! In retrospect this one would be better served by a larger instrument, but it was fun to do. I especially like the interacting galaxies, of which there are several in this field. I did a lot of stretching during processing and it's a noisy image as a result. I did a little noise reduction in Images Plus but after trying more agressive noise reduction techniques I decided I preferred it this way. The image could use a lot more exposure time.
