Visual magnitude and apparent dimension (arc min unless indicated as arc sec) Remarks The First 30 NGC objects By Paul Markov, October 1999. Its designation in the New General Catalogue is NGC 581. I have therefore looked at the range of magnitudes in different wavelength ranges in several references, and at the visual magnitude estimates in Steve Gottlieb's visual examination of the NGC/IC objects. "Best" objects are marked in bold. Given its visual magnitude of 12, NGC 6804 is visible with the help of a telescope havng an aperture of 8 inches (200mm) or more. Some objects originally thought to be deep sky objects and listed in the NGC have been subsequently shown to be ordinary stars, so their inclusion in the catalog is now considered erroneous. Messier 46 (NGC 2437) is an open cluster with an apparent magnitude of 6.5. The population in the background of open clusters: tracer of the Norma-Cygnus arm We present colour-magnitude diagrams of open clusters, located in therange 112° l 252°, manifesting stellar populations inthe background of clusters.Some of the populations are found to belocated beyond the Perseus arm and may be the part of the Norma-Cygnus(outer) arm. Typical of reflection nebulae, they appear bluish resulting from light reflection from hot young stars by the interstellar dust, with darker regions dividing the three NGC objects. If unchecked, all the objects will be displayed irrespective of brightness. Physical Information: The asterism consists of five 14th to 15th magnitude stars arranged in a north-south oval, and a few much fainter stars that Cooper could not have seen; so the NGC object is basically just the five brighter stars. Only 35' to the southwest is the dauntingly dim object called the Bubble Nebula (NGC 7635), an even fainter ring of gas, whose brightest section abuts a 9th-magnitude star. Messier 46, also designated as NGC 2437, is an open cluster that was discovered in 1771 by famous astronomer Charles Messier. The Interactive NGC Catalog Online by Hartmut Frommert.

M31 is best viewed during winter, is magnitude 4.5 *, and can be viewed with naked eye. Stars. The absolute magnitude of the variablewas determined from the period-luminosity (P-L) relation for Galacticδ Scuti stars and from theoretical modeling of the observed B,V,Ilight curves with nonlinear pulsation models. Objects are sorted by catalog number, starting with Messier list, then NGC, IC and so on. There are 3 Messier Objects located in the constellation of Puppis, namely the Messier 46, Messier 47, and Messier 93 open clusters. This list of stars is based on the 'NGC 2000.0' version of the catalog, which lists the stars in its errata, supplemented with data on each individual star from the VizieR database. Some of the populations are found to belocated beyond the Perseus arm and may be the part of the Norma-Cygnus(outer) arm. We present colour-magnitude diagrams of open clusters, located in therange 112° l : 252°, manifesting stellar populations inthe background of clusters. NGC 6993 - The object is declared as "not found" in the RNGC and so the type is "-" in Sinnott's book. In thispaper we analyze the STEPSS observations of the open cluster NGC 1245 todetermine the variable-star content of the cluster. ... previous HST imagingdata. The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his Catalogue des Nébuleuses et des Amas d'Étoiles ("Catalogue of Nebulae and Star Clusters").
