Arp 199, SDSS

Arp 199, NGC 5544 and 5545. Boo. Inside a fan-shaped asterism with 3 stars on S and E side and one on NW side. Threshold star forms a right triangle [equilateral] with the cores of -44 and -45 close to the NW. NGC -44 small, round, has a bright center. -45 extends to the ENE and connects to the SE side of -44. It has a core elongated along the major axis and an arm that extends from the SE side of the core to the ENE end of the galaxy, then turns diffusely and broadly to the NW. Peripheral structure in -44 is not seen. In the Herschel catalog. [Seen previously with a 12" SCT as a double, connected object with one elongated component.]
