One of the astronomical targets I most enjoy photographing yet rarely makes it to my website is galaxy clusters. The wonder of photographing such plentiful distant words is easily captivating.
It often amazes me how many rarely seen distant galaxies can be plucked from the night sky in a photograph only one field of view large, in this case much less than a degree in size at 21 minutes by 14 minutes in size (about 1/4 the visual size of the Moon). Here we have 25 galaxies easily able to be identified, likely many others masquerading as faint stars. I stumbled upon this cluster when it was photographed by my backyard semi-automated supernova search program which photographs about 400 galaxies every clear night (other commitments permitting!).
There is so much waiting to be photographed by amateur astronomers.
