Distance: 7,600 light years (2,300 parsecs) Also known as h and χ Persei, the Double Cluster (comprising NGC 869 and NGC 884) is a "line of sight" pairing in the constellation in Perseus, though actually they are only a few hundred light years apart. Apparent size: 30′ The Double Cluster (NGC 884) - posted in Sketching: Started today at 2am to make a crack at a few new targets. The western component of the pair, h Persei, entry 689 in the New General Catalogue (NGC 689), is about 5.6 million years old, while Chi Persei (NGC 884) is closer to 3.6 million years old. Designations: NGC 869, Collinder 24, Melotte 13, h Persei, Right ascension: 02h 22.0m Apparent magnitude: +3.7 This is an excellent targer both for binoculars and a telescope. Ptolemy listed the cluster as of the seven “nebulosities” in his Almagest. NGC 869 has a mass of 3700 solar masses and NGC 884 weighs in at 2800 solar masses; however, later research has shown both clusters are surrounded with a very extensive halo of stars, with a total mass for the complex of at least 20,000 solar masses. There are some blue giants in here too. The Luminance filter was used for longer than the other three as this is where almost all the details come from. Designations: Double Cluster, Caldwell 14, NGC 869 and NGC 884, h Persei and χ Persei, Right ascension: 02h 19.1m Each cluster contains more than 300 blue-white supergiants and their hottest stars on the main sequence belong to the spectral class B0. Both can be seen with the unaided eye and are usually easy to find if you are observing from a dark location. Probably, he used the name "h Persei" for a fainter nearby star. The Double Cluster is the name for two open clusters – NGC 869 and NGC 884 – located close together in Perseus constellation. Mass: 2,800 solar masses With an apparent magnitude of 3.7/3.8, the Double Cluster is visible even without binoculars in good conditions, but best observed with binoculars or small telescopes. It is circumpolar from most northern locations. A pair of star clusters, collectively known as the Double Cluster, shines from the constellation Perseus. Learning the constellations is difficult.

It makes a beautiful sight in a telescope of any size, and is downright stunning in a moderate-sized telescope equipped with a wide-angle eyepiece. Have you ever wanted to look up to the night sky, name any pattern of stars and be able to tell their stories? We had no choice but to image this target unguided. The clusters are only a few hundred light-years apart; imagine the night sky from a planet orbiting any star nearby! But open clusters NGC 869 and NGC 884 are doubly impressive. The Double Cluster (also known as Caldwell 14) consists of the open clusters NGC 869 and NGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. I may make this a mosaic and capture the other half to complete it. Even under moderately dark skies, the double cluster in the constellation of Perseus is easily seen with the naked eye. Both clusters contain a significant number of bright, young O and B-type stars. We imaged the Double Cluster in Perseus with 4 filters: As with most of our images, we like to show you the stacked image for each individual filter, sadly, these files are lost for this particular target. Mosaic of 3 LRGB images. Magnitudes are given without a decimal point, e.g. They are both part of the so-called Perseus OB1 association, an assembly of extremely massive stars. Both NGC 869 and NGC 884 are getting closer to Earth at a rate of 24 miles per second. Easy to spot in the northern winter sky between the constellations of Perseus and Cassiopeia, the Double Cluster is a favourite of amateur astronomers.

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. Both are very similar to each other in size, magnitude, and age. 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. 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. It is the easternmost of the Double Cluster with NGC 869. The Double Cluster (h and Chi Persei; NGC 869 and NGC 884) consists of two young open clusters that lie close together in the sky in Perseus and are visible to the naked eye on a clear, dark night as a hazy patch of light. View full resolution image. Double Cluster location in Perseus. Written By Jason Matter. We analyze eight sources with strong mid-infrared excesses in the 13 Myrold double cluster h and χ Persei. These are catalog numbers in the New General Catalogue of celestial objects, fist established by John Dreyer in 1888. NGC 957 is much smaller and really isn't that impressive looking, but it is always nice to add an extra deep sky object in your image if you can! godine. But open clusters NGC 869 and NGC 884 are doubly impressive. NGC 884 is a Open Cluster in the Perseus constellation.NGC 884 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. The Double Cluster is a large, bright and easy target to photograph for any amateur astrophotographers. Just as the pioneers of astronomy did in their time, look up and take notes of your observations as you are the author of this star-filled journey. Learn how to find each object in the night sky, and read our recommendations on imaging them in a quick and comprehensive way. NGC 869 and 884 are often designated h and χ Persei, respectively.
