![]() Called the Owl Cluster, it is located 2.1° SSW of Ruchbah (Delta Cassiopeiae). 6.4), large (13'), pretty rich cluster with stars from mag. Also, while you fit everything in a 1° field, you will do better keeping Navi out of the field.Ħk GIF NGC457 (Best 14, Caldwell 13) is a bright (mag. The plates are somewhat blue sensitive, though. The photograph from the Digital Sky Survey suggests you may have better luck with IC63. Dreyer's little "remarkable" code sits after the size description, rather unusual. Both are fairly faint and extremely large. 5° north and north-east of Navi (Gamma Cassiopeiae. From the Digital Sky Survey.ħ1k JPEG IC59 and IC63 are parts of a reflection nebula located. A notable feature is the tight, arrow shaped cluster pointing south, and an arc of stars to the ESE. ![]() This is a mag 10.6 grouping with members at mags 12.5 and fainter. Image by Marco Lorenzi taken on film through an 8", f4, coma corrected Newtonian.Ĥ7k JPEG Object 4 (Be4) in the Berkeley University Catalog of open clusters. The nebulosity, sometimes called the Pacman Nebula, responds to filters, and even better to photography. 7), very large (35'), diffused, with a small triple star on the northwest edge. Dreyer's description reads as follows: Faint (mag. From the Digital Sky Survey.Ħ4k JPEG NGC281 (Best 13) is an open cluster with nebulosity located 1.7° east of Shedar (Alpha Cassiopeiae). It is located 5.4° south of zeta Cassiopeiae. Dreyer says it is "resolvable," meaning there are dark markings in the middle. 9.2), very large (14'x12'), irregular shaped dwarf elliptical galaxy with a less pronounced core than its companion NGC147. From the Digital Sky Survey.ġ1k JPEG NGC185 (Best 12, Caldwell 18) is a pretty bright (mag. It is located 5.4° south of Zeta Cassiopeiae. 9.3), very large (13'x8'), irregular shaped dwarf elliptical galaxy with a bright core accented by foreground stars at the core. It is 1.2° SSW of Caph (Beta Cassiopeiae).Ģ4k JPEG NGC147 (Caldwell 17) is a very faint (mag. Included are both the Digital Sky Survey image, and a detailed map from The Sky for Windows, the latter showing the spectral colors of the brighter stars. Image taken with a HISYS 22 on a 4" Meade at f6.3.Ĭalled "anon" by Jeff Bondono, this is not an object as such, but an interesting star field of doubled stars. Messier thought he saw nebulosity, but there is none. A multilingual web site, most of the information is available only in German.ģ2k JPEG M52 (NGC7654) is a large (13'), condensed, rich open cluster on the western border of Cassiopeia. Color image on the right by Beat Kohler and posted on Astro Info, a service of the Swiss Astronomical Society. Image on the left from the Digital Sky Survey. Easy to find, this cluster sits mid-way between Sigma and Rho Cassiopeiae. Opinions vary as to whether 300 or 1000 stars reside here. 6.7, Dreyer describes it as very large (16'), very rich, very much condensed, with stars mags. NGC7789 (Best 16) is an open cluster that improves with aperture. Here are wide angle and narrow angle views. NGC7635 (Caldwell 11) is the Bubble Nebula, a small (15'x8'), dim bit of nebulosity several minutes across. ![]() The good stuff is a splash of muticolored stars 30' to the NW. You find it on the bottom end (south) of the image, 2/3 to the left (east). Its size is listed as 20', and it contains stars mag 8 and fainter.

The next views are binocular width, showing stars to mag. The first map is a wide area view of the constellation, suitable for naked eye browsing. While they are quite large, they are all about 50k, and so are easy to view at today's modem speeds. Each map, therefore has a second link to a map better suited for printing in a graphics program, and using in the field. They sport red labels, which look good on screen, but which disappear when used with red flashlights.
