NGC 5907, the Splinter Galaxy, in the upper left corner, is a very slender edge-on spiral galaxy with a small central bulge and a pronounced dust lane. The dust lane shows some wonderful detail and tints the core a beautiful amber color. The galaxy itself is something of a giant lying 59 million light years away and 180,000 light years across. M102, in the lower right corner, is a beautiful edge-on spiral galaxy that is nestled in between Draco, Bootes, and Ursa Major. It is almost exactly edge-on to our line of sight and shows an extremely thin profile with only a slight central bulge and a slender dust lane. In the lower left corner is another edge-on spiral, NGC 5908, and a tiny face-on spiral, NGC 5905.
M102 and NGC 5907 are currently high overhead at dusk.
