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. 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. The cluster lies at an approximate distance of 4,000 light years from Earth. Apparent size 0.85 by 0.35 arcmin. dark nebulae) are also listed. Caroline’s Cluster.

This spiral galaxy was discovered by Messier in 1780. Objects without magnitude (i.e. By how much does the apparent magnitude change? Some of the populations are found to belocated beyond the Perseus arm and may be the part of the Norma-Cygnus(outer) arm. In thispaper we analyze the STEPSS observations of the open cluster NGC 1245 todetermine the variable-star content of the cluster. The spiral arms of M66 appear deformed due to the gravitational effec… Pre-main sequence stars in open clusters. 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. NGC 5350 Group: 13h53m24s +40°22' Canes Venatici: This group is positioned near a 6.5 magnitude star and has a bright spiral galaxy, NGC 5471 less than a half degree to the northeast. The higher the magnitude of an object, the fainter it appears. M31 is best viewed during winter, is magnitude 4.5 *, and can be viewed with naked eye. The cluster lies at a distance of 10,000 light years from Earth and has an apparent magnitude of 7.4. 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. This is the interactive NGC (and IC, and Messier) catalog at SEDS, based on the famous NGC 2000.0 by R.W. Messier 46, also designated as NGC 2437, is an open cluster that was discovered in 1771 by famous astronomer Charles Messier. "Best" objects are marked in bold. How much brighter is a magnitude +2 star than a magnitude +4 star? Only some minor corrections have been included in our online database. – Constellation: Canis Major. Available Resources for NGC 2608 - Spiral Galaxy II. 3. There are 3 Messier Objects located in the constellation of Puppis, namely the Messier 46, Messier 47, and Messier 93 open clusters. – Object type: Open cluster.

Messier object M31 (NGC 224), also known as the Andromeda Galaxy, is a spiral galaxy located in the constellation Andromeda in the Local Group of galaxies. astronomical catalogue of deep sky objects Spiral Galaxy NGC 3982 displays numerous spiral arms filled with bright stars, blue star clusters, and dark dust lanes. It issuggested that each of these objects had two parent clusters, one with ared horizontal branch and another with a blue horizontal branch. 2. The cluster has an apparent magnitude of 7.1. A good object for f/2 Fastar imaging. Messier object M51 (NGC 5194), also known as the Whirlpool Galaxy, is a spiral galaxy located in the constellation Ursa Major in the M51 Group of galaxies.

Small Magellanic Cloud, field of NGC 330 Aims.We search for the effects of metallicity on B and Be stars in theSmall and Large Magellanic Clouds (SMC and LMC) and in the Milky Way(MW), by extending our previous analysis of B and Be star populations inthe LMC to the SMC. The New General Catalog (NGC) is a listing of nearly 8,000 non-stellar objects, such as star clusters, nebulae, and galaxies, compiled by J.L.E.

Together with M65 and NGC 3628, the three galaxies are referred to as the Leo Triplet or the Trio in Leo. IV. See also rise and set times. It spans about 30,000 light years, lies about 68 million light years from Earth and can be seen with a small telescope in the constellation of Ursa Major. Messier 47 (M47) Messier 47 (NGC 2422) is an open cluster in Puppis. – Magnitude: +3 – Distance: About 1,321 light years – Other designations: C 1104-584, Caldwell 91, Melotte 103, Football Cluster, Wishing Well Cluster. For example, Sirius has a magnitude of –1.46, while the brightest planet, Venus, can reach magnitude –4.9 at its brightest. Overall it shines at magnitude … This grouping is positioned half a degree northeast of the great nebula. 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. NGC 7331 is the brightest member of the NGC 7331 Group of galaxies. It has an apparent magnitude of 10.4.
