Quote:Your C8 should do the trick, actually. But as always in regards to resolving clusters, both the darkness of your skies and use of high power (and good seeing) are important factors. Here are my notes through a variety of apertures ---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.80mm (1/20/07): visible in the finder at 13x as a very faint, small glow about a half-degree SW of M35.

Quote:Just tonight I looked at NGC-2158 with my 15-inch from the driveway. To my surprise, some stars were resolved despite the milky skies and a streetlight across from my house. So it appears NGC-2158 is not quite as hard to resolve as I thought. It showed up quite nicely at 227X.Taras
