	Open Cluster M34 - Wikipedia, the free encyclopedia
		Open Cluster M34 (also known as Messier Object 34 or NGC 1039) is an open cluster in the constellation Perseus.
		M34 is at a distance of about 1,400 light-years away from Earth and consists of some 100 stars.
		The cluster is just visible to the naked eye in very dark conditions, well away from city lights.

	Messier Object 34
		Considering the spatial motion of M34 and other clusters, O.J. Eggen (1983) found it co-inciding with that of several others, including the Pleiades (M45), NGC 2516, IC 2602, the Alpha Persei Cluster (Melotte 20) and the Delta Lyrae Cluster (Stephenson 1).
		M34 was probably first found by Giovanni Batista Hodierna before 1654, and independently rediscovered by Charles Messier in on August 25, 1764.
		Open cluster M34 can quite easily be found (even with the naked eye under good conditions as a faint nebulous patch) as it lies just north of the line from Algol (Beta Persei) to Gamma Andromedae.

	Messier Guide: Late Autumn
		M34 is a large, bright, coarse open cluster, a pleasant change from faint galaxies and miniscule planetary nebulae.
		M34 is fairly easy to find by the point-and-shoot method, lying about 1 degree N of a line connecting Beta Persei (Algol) and Gamma Andromedae (Almach), about 40% of the way from the former to the latter.
		M34 is small and tight in my 7x35 binoculars, especially under suburban skies or better, where five of the stars resolve easily.

	Open Star Clusters
		Over 1100 open clusters are known in our Milky Way Galaxy, and this is probably only a small percentage of the total population which is probably some factor higher; estimates of as many as about 100,000 Milky Way open clusters have been given.
		The first open clusters have been known since prehistoric times: The Pleiades (M45), the Hyades and the Beehive or Praesepe (M44) are the most prominent examples, but Ptolemy had also mentioned M7 and the Coma Star Cluster (Mel 111) as early as 138 AD.
		All the diffuse nebulae in Messier's catalog are associated with open clusters of young stars which have formed of the nebula's material in (astronomically) very recent times, and are still formed today in many cases.

		Meynet's Geneva Team) open cluster of about 100 stars (according to H.S. Hogg) lies about 1,400 light years and is scattered over 35 arc minutes, more than the diameter of the full Moon.

	Undergraduate Thesis
		This research falls under the auspices of the WIYN Open Cluster Study (WOCS), which was established tocreate a database of open cluster photometry, astrometry, and spectroscopy.
		Cluster members are thought to have formed at the same time and out of the same material and can therefore be used to study specific astrophysical problems.
		I chose NGC 2420 because it is the nearest metal poor open cluster known and it is very rich.

	Robert Bruce Thompson's Winter Messier Objects Presentation - M34
		M34 was discovered by Giovanni Batista Hodierna before 1654, and re-discovered independently by Charles Messier on August 25, 1764.
		At about 180 million years old, M34 is a middle-aged open cluster, which has about 100 member stars, ranging from magnitude 7.9 down.
		M34 is visible as a bright luminosity near the other edge of the field.

	openclusters
		The stars are usually relatively young suns, because with time the stars in an open cluster tend to drift apart, so that stars from "old" open clusters are no longer clustered stars.
		Our own sun probably arose in such a cluster, perhaps including some of the stars of the Big Dipper, that seem to move through space together with our sun.
		M34 is a beautiful sight in binoculars or small telescopes, with the dozen brightest stars in the cluster standing out brilliantly.

	M34 - Open Cluster in Perseus
		M34 is a bright open cluster of stars in the constellation of Perseus.
		The cluster is easily visible with the aid of binoculars and is readily resolved even in small amateur telescopes.
		The cluster’s visual diameter is a little larger than that of the full Moon.

	Observations of object "M34"
		The Cluster was very obvious and the amount of stars in the FOV is always overwhelming to me. Even though the FOV in my telescope at my lowest power (30x) is about half of what it is in the binos, the number of stars is 4 times as much.
		M34 open cluster has many faint stars in it.
		In the binoculars it was a pretty little cluster, with a half dozen bright stars, especially 2 oriented roughly E-W toward the center with a bright fuzzy patch between them (presumably the unresolved core).

		Star clusters are just what they appear to be, as few as 20 to as many as several hundred stars grouped tightly together in a cluster.
		What you will be looking at is a galactic cluster of relatively young stars, approximately 140 light-years away, that formed about a billion years ago (considering the age of the universe is estimated to be about 15 billion years old).
		Also in the constellation of Taurus is another open cluster, the famous "seven sisters of Pleiades" (M45), so named because you can see seven (magnitude +3.0) stars with your naked eyes.

		The image doesn't do the cluster justice since the field of view is so restricted on the TC255 chip.
		This is another big cluster that is almost better in the view finder than in the scope itself, use your widest angle and lowest magnification eyepiece.
		This was a much smaller cluster that had some nebulostiy in the center where I couldn't resolve stars all the way.

	Citebase - Rotational Studies of Late-Type Stars. VII. M34 (NGC 1039) and the Evolution of Angular Momentum and ... (Site not responding. Last check: 2007-09-10)
		We analyze Keck Hires observations of rotation in F, G, and K dwarf members of the open cluster M34 (NGC 1039), which is 250 Myr old, and we compare them to the Pleiades, Hyades, and NGC 6475.
		A few K dwarfs in M34 are still rapid rotators, suggesting that they have undergone core-envelope decoupling, followed by replenishment of surface angular momentum from an internal reservoir.
		Our comparison of rotation in these clusters indicates that the time scale for the coupling of the envelope to the core must be close to 100 Myr if decoupling does, in fact, occur.

		From a bright 7th-magnitude star in the southeastern part of the cluster it's an easy star hop along a string of 10th-magnitude stars to a pair of stars of about the same brightness.
		All but lost in the glare, and just northwest of the star itself, you may be able to spot a faint circular patch a bit more than half an arcminute wide.
