Steve's Notes

===== NGC 613 30" (10/15/15 - OzSky): this very large barred spiral was a stunning showpiece at 303x! The bright central bar region is oriented NW-SE and extends ~2.5'x1' with the halo and arms stretching ~5'x3.6'. The central region is sharply concentrated with a very intense core that increases to a bright stellar nucleus. A prominent spiral arm is easily visible on the southeast end. It has a well defined edge and a high contrast as it emerges from the central region and unfurls east and north. The arm then dims but can be followed as it bends backwards on the east side towards the northwest! The arm dims out before reaching a mag 9.6 star 2.2' NE of center. A second bright, well-defined arm is attached on the northwest end and curls south on the west end of the halo. 17.5" (12/4/93): fairly bright, very elongated 3:1 WNW-ESE, 4.0'x1.3', prominent elongated core, almost stellar nucleus with direct vision. ÊThe halo is broader with averted vision. ÊSoutheast of the core there appears to be a very faint extension or large knot. The DSS reveals this feature to be the bright spiral arm extending southeast from the central bar. ÊLocated 2.4' SW of mag 9 SAO 167149. 8" (11/28/81): faint, moderately large, diffuse, small bright core. ÊA mag 9 star lies 2.5' NE.
