NGC 4605: Peculiar Galaxy (Ursa Major) RA: 12h 40.0m / DEC: +61° 36'.7
Instrument: 18-inch Obsession

This interesting galaxy resides in the far northern sky in Ursa Major. 3.3 magnitude Megrez, the northeast corner star in the bowl of the Big Dipper, lies 5.5 degrees to the southwest. My sketch presents a 199X view in the big Obsession. NGC 4605, a 10.3 magnitude barred spiral, is centered. Its irregular form reminds me of a dolphin in mid-leap above the waves. Is this from tidal interaction with another stellar gotham? Or just the natural shape of an active galaxy? In any event, NGC 4605 covers a 3'.5 by 1'.2 area with a 14th magnitude GSC star standing along the southwest edge. Another twelve stars dot the field. These range from 10th to 15th magnitude in brightness.
