There are SEVEN galaxies captured in this one image. Can you spot them all?

This image was taken from my backyard in Georgetown, TX. I continue to be impressed by the Astronomik CLS filter. At least 1 hour of this image was washed out by floodlights from a neighbor, but the subs bore little difference from ones taken when the lights were off.

This is an image of Bode's Galaxy (and the smaller Cigar Galaxy to the left). These galaxies are located in Ursa Major (the Big Dipper) and are some 12 million light years distant. This is one of the most striking examples of a fully structured spiral galaxy. Our own Milky Way galaxy is also a spiral type. Bode's galaxy is lies some 300,000 light years from the Cigar Galaxy (M82 on the left). These galaxies are actually experiencing a constant gravitational interaction with one another. The strong pull from Bode's galaxy has caused severe deformation in the Cigar Galaxy (sometimes called an unstructured galaxy). The constant siphoning of hydrogen from one galaxy to another has caused an unprecedented level of new star formation (10x faster than in the Milky Way) within the Cigar galaxy (by virtue of lumping Hydrogen together). As such, its surface brightness is very high coming in at five times brighter than the Milky Way. The Cigar Galaxy is viewed as edge on, but it does not have a very defined structure.

These two galaxies belong to a group of galaxies some 34 members large of which Bode's Galaxy is the largest.
