NGC/IC Project Restoration Effort

===== NGC 4809 and NGC 4810 are an interacting pair of late-type irregulars. While the NGC entry does not tell us which is which -- there is a single position for both, and it is wrong by a minute of time and 6-7 arcminutes -- by convention NGC 4809 is the larger northern object. Neither galaxy has an apparent nucleus, so the positions I've chosen from the SDSS are simply approximations of the centers of the bars for each. Better positions might be pulled in from surface photometry as the centers of the isophotes for the galaxies.

===== NGC 4809 48" (5/4/16): at 610x; moderately bright, elongated 7:2 WSW-ENE, ~1.2'x0.35'. This galaxy has an unusual irregular "banana" shape with a patchy appearance; it bends slightly south on the east-northeast end and has a blunter west-southwest end that also twists slightly south. There is a slightly brighter patch that is offset just north of the geometric center. I assumed this was the core region, but on the SDSS it appears to be a large HII region and there is no central core. A second slightly brighter patch is at the west-southwest end and this is clearly an active star-forming complex on the SDSS. NGC 4809 is the larger member of an interacting pair with NGC 4810 just 0.8' S. 18" (3/30/05): very faint, very small, slightly elongated. This galaxy is nearly attached to the north side of NGC 4810. Although smaller (must have viewed only a portion as the size is larger on the DSS), it may have a higher surface brightness.
