I don't know what possessed me to image a bunch of tiny, super-dim, wide-band objects from my light polluted back yard, but I'm glad I did. As is usually the case with my back yard projects, the processing of this image was an exercise in pulling useful signal out of the copious noise. I made heavy use of masks and different noise reduction techniques. The result, I think, is pretty good. If I were to do it again, I would double the focal length to get more resolution in the heart of this galaxy cluster.
