NGC 2158
18" (2/24/06): at 323x, this rich, irregularly shaped cluster is beautifully resolved into 45-50 stars that are peppered over a 5' background glow. Appears like a resolved globular of low concentration class. Includes a couple of dozen mag 13.5-14.5 stars along with a rich carpet of fainter mag 15 stars. There are several close pairs (1"-2" and possibly closer) and the number of stars keep increasing in moments of rock steady seeing as they seem to emerge from the background. A single brighter star is at the east edge.
17.5" (2/8/86): 30-35 stars resolved, unusually rich, compact, about 5' diameter. The appearance is similar to a resolved globular cluster. Located 30' SW of M35.
13.1" (2/16/85): at least 20-25 stars resolved at 415x.
13.1" (11/5/83): ~15-20 stars, mottled clump near SE edge.
8": few stars resolved over haze.
13x80mm (1/20/07): visible in the finder as a very faint, small glow about a half-degree SW of M35.
