It is the easternmost of the Double Cluster with NGC 869. Of the dozens of open star clusters scattered across the autumn sky, none is finer through binoculars than NGC 869 and NGC 884, the famous Double Cluster in Perseus. The clusters are dominated by bright blue stars and, speckled with a few fine orange stars, make a spectacular sight in the night sky, especially through binoculars. The Double Cluster, is NGC 884 and NGC 869, a group of two open star clusters in the Perseus constellation.It has many blue and red stars. Distance: 7,600 light years (2,300 parsecs) The clusters are about 7,500 light-years from us. There is a little heiroglyphic character at the heart of NGC … Also known as h Persei and χ Persei, the clusters both lie at an approximate distance of 7,600 light years from Earth and are about 12.8 million years old. Written By Jason Matter. Each cluster contains more than 300 blue-white supergiants and their hottest stars on the main sequence belong to the spectral class B0.

Now known respectively as h and chi Persei, or NGC 884 (to the east, or left, of the image) and NGC 869 (the cluster to the west, or right, of the image), the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun. Represents the jewels from the handle of Perseus’ sword, Total mass of at least 20,000 solar masses. The Double Cluster (NGC 884) - posted in Sketching: Started today at 2am to make a crack at a few new targets. NGC 884 Part of the Double Cluster. Find: During my "winter observations" in February 2017, I tried to find the double cluster NGC 884/869 in Perseus. Designations: Double Cluster, Caldwell 14, NGC 869 and NGC 884, h Persei and χ Persei, Right ascension: 02h 19.1m Both visible with the naked eye, NGC 869 and NGC 884 lie at a … NGC 884 (also known as χ Persei) is an open cluster located 7600 light years away in the constellation of Perseus. Mosaic of 3 LRGB images. We show that the material with T~300-400 K andLd/L*~10-4 to 10-3 producesthe excesses in these sources. Français : Le double amas de Persée , est constitué de deux amas ouverts : NGC 884 et NGC 869. Open clusters NGC 884 and NGC 869 form the Double Cluster in … The clusters are only a few hundred light-years apart; imagine the night sky from a planet orbiting any star nearby! Also known as "h and chi Persei", this unusual double cluster, shown above, is bright enough to be seen from a dark location without even binoculars. These clusters are relatively young and do contain several red super giants which I think really add to the visual appeal of this one. Sometimes called the h Persei Cluster, this is an open cluster in the constellation of Perseus and is a member of the Perseus OB1 association. That is relatively close-by (the Milky Way galaxy has a diameter of roughly 100,000 light years.) Starlight Express MX-916 on 3.5" Questar. Probably, he used the name "h Persei" for a fainter nearby star. The Double Cluster has been known since ancient times, but first catalogued only around 130 BC, when the Greek astronomer Hipparchos mentioned it as a “nebula” or “cloudy spot” in his writings. Learning the constellations is difficult. First Light Guides #10 and #11 are a combined guide, as both NGC 869 and NGC 884 would be wonderful objects to observe on their own.
