OPEN CLUSTERS

OPEN CLUSTERS FOUND TO DATE: M29, M35, M36 , M37, M38, M39, M41, M44, M45, M50, M52, M67, M93, M103, NGC 225, NGC 457, NGC 654, NGC 659, NGC 663, NGC 1981, Double Cluster, Hyades.

M29: In the constellation Cygnus. This cluster appears to have a dipper shape without a handle. Bright and easily seen. Fairly easily picked out from the surrounding star field. M29 is about a Magnitude 6.6 cluster.

M35: In the constellation Gemini. This is a very nice Open Cluster. Stars are resolved and it is easily picked out from the surrounding star field. A nice view through the telescope using low to medium magnifications.

M36: A nice Open Cluster at about Magnitude 6. It is located in the constellation Auriga, two other Open Clusters lay nearby. When viewed with the telescope stars are resolved and it makes a nice view. Fairly easily picked out from the background sky as it is not in a very star dense region of the sky.

M37: Another nice Open Cluster in the constellation of Auriga. This Open Cluster is about Magnitude 5.6 and is the brightest of the Auriga trio. A very nice sight in the telescope. Stars are easily resolved. Best viewed with Low to Medium power.

M38: The faintest of the Auriga trio, at about Magnitude 6.4. I found this to be the most impressive of the Auriga Open Clusters. It is not too tightly packed and the stars are dispersed through out the cluster. It is a very nice view in the Telescope and all three of the Open Cluster in Auriga are well worth tracking down.

M39: A large cluster with many bright stars dispersed through out it. Located in the constellation Cygnus at about Magnitude 4.6. Worth hunting for!

M41: This is a great sight in the telescope! This cluster is large and dense! Stars are compressed together towards the center. At Magintude 4.5, this is a great object! In the constellation Canis Major.

M44: The Beehive Cluster! This is a large open cluster located in the constellation of Cancer. It looks like a bunch of bright stars scattered all over. It dose seem to resemble a swarm of bees in flight. A great cluster! And fairly easy to find, although the guide stars are quite faint.

M45: The grand Pleiades... a very nice view through the telescope at low magnification powers. This cluster is visible to the naked eye!! It looks like a mini dipper when in the sky. Through the telescope it is amazing, many stars are scattered all over the cluster. But the Pleiades is even better through Binoculars. A very nice cluster which is very obvious in the sky!

M50: This is a medium sized dense cluster. Located in the Constellation Monoceros. M50 shines at Magnitude 5.9, making it an easy binocular object!

M52: This is a small, very compact cluster. Stars are resolved. Located in the constellation Cassiopea. About Magnitude 6.9.

M67: A small, compact cluster. Located in the constellation Cancer. This is a dense cluster, with many stars easily resolved. Magnitude 6.9.

M93: This is a large open cluster in the constellation Puppis! Stars are somwhat compact and are dense! This is a great Open Cluster! It is magnitude 6.3! And is a easy find!

M103: This is a small open cluster in cassiopea. It appears triangular in shape and has few stars visible. Easily seen and picked out from the surrounding field.

NGC 225: A cluster with stars scattered through out. In the constellation Cassiopea. Quite large, larger than NGC 654. Stars are easily resolved. Cluster is of Magnitude 7.0.

NGC 457: The ET Cluster. Open cluster with two bright stars nearby. Stars are easily Resolved. Many stars are visible, cluster appears large in size. In the constellation of Cassiopea, this cluster shines at Magnitude 6.4.

NGC 654: Cluster with a bright star. Small, but appears larger than NGC 659. Some stars are resolved. Mostly appears as a patch of light. Found by following three bright stars close to NGC 663. The third bright star is the cluster.

NGC 659: Small cluster near NGC 663. Two stars appear to come in and out of resolution. Appears as a small patch of light near a triangle of bright stars.

NGC 663: This is a large open cluster in cassiopea. It appears as big grouping of stars in a w or m shape. The stars are quite compact but also seem spread out in the telescope. Similar in size to NGC 869. NGC 663 is bright in the telescope and easily picked out from the surrounding star field. Cluster is Magnitude 7.1.

NGC 1981: Open Cluster in the constellation of Orion. Large cluster, with bright stars. Stars are easily resolved. Stars are scattered through out the cluster. Cluster is Magnitude 4.6. Appears close to M42.

Double Cluster: This is an absolute wonderful Open Cluster!! It is actually two clusters NGC 884 and NGC 869, hence the name Double Cluster. Visible to the naked eye as faint fuzzy patch in my backyard. Telescopically it is a very beautiful sight. Hundreds of stars are visible at low magnification. The two clusters are fairly compact in the center but spread out towards the edge. A very nice sight!! This is also a wonderful sight through Binoculars! Increase the Magnification and observe the clusters one at time. A very nice object.

Hyades: This cluster is too spread out for the telescope. It is best viewed with Binoculars. Its a bunch of stars scattered around Aldebaran in Taurus, the bull.
