The Thirty-Something Collection

On December 29th I had a chance to give my new telescope mount a spin. I decided to take images of the "thirty-something" Messier objects (M31 - M39, less M30 which is not visible).

Hope you enjoy the pictures as much as I had viewing and imaging them.


M31, The Andromeda Galaxy is the brightest galaxy visible from Earth and is an easy naked-eye and binocular target for star gazers. M31 has two close neighbors, M32 and M110, both of which are much smaller and will eventually be absorbed by M31. This Grand Galaxy lies 2,900 light years (ly) from Earth and is due to collide with our galaxy, The Milky Way in about 1-Billion years. M31 was referred to as the "little cloud" to famous Persian astronomer Al-Sufi who depicted the object in his Book of Fixed Stars in 905AD.

M32 (at center, M31 is lower-right) is a companion galaxy of M31 and will eventually be absorbed by its huge neighbor.

M33 the Triangulum Galaxy (also the Pinwheel) is a spiral galaxy that is a companion of its much larger neighbor, the Andromeda Galaxy. M33 is 3,000 ly from Earth and is moving toward our solar system at a rate of 240 km/s. Don't worry though, at that rate it will take a billion years or so to get here.

M34 is an open star cluster in the constellation Perseus. It consists of about 100 stars and lies about 1,400 ly away from Earth. The object is naked-eye visible under dark sky conditions and can be seen any evening in the Fall, Winter and early Spring.

M35 is an impressive open star cluster that lies in the constellation Gemini. The cluster consists of several hundred stars, many of which are brighter than magnitude 13. M35 covers an area larger than the Moon, is 24 lyacross and is about 2,800 ly from Earth.

M36 is one of three bright open clusters in the constellation Auriga. M37 and M38 are the other clusters. From our perspective M36 measures 14 ly across and is 4,100 ly from Earth.

M37 is the brightest of the three Auriga open clusters. It contains over 500 stars, 150 of which are brighter than magnitude 12. M37 is 4,400 ly from Earth and spans 24 ly across.

M38 is the last of three open clusters in Auriga. Lying very close (2.5 degrees north) of M36, this is 4,200 ly from Earth and 25 ly across. It contains a very large yellow star that would dwarf our meager Sun many-fold. Some astronomers have seen a 'cross' pattern in some of the brightest stars while others have seen the math symbol 'Pi'. I will leave you to decide what pattern, if any you see in M38.

M39 is an open cluster in the constellation Cygnus. The cluster is 800 ly away and a about 7 ly in diameter. M39 contains 30 proven member stars, though some star catalogs put the number closer to 50.

My next outing (when the rain stops & clouds part) will include a journey through the constellation Orion.

There are several sky treasures to discover in that group of stars.

I just need to wait for the weather to cooperate.

Clear Skies


@@@

Finally! A Clear Night

If you live in Northern Virginia and are sick of the cloudiness, I apologize. It was all my fault. How dare I buy a new telescope and hope for clear skies to actually enjoy the darn thing.

A couple nights ago the clouds parted, so I high-tailed it outside to do some star-gazing. I squeezed in a couple hours of observing time before the clouds rolled in.

Here are some pictures from my outing.


M34 (Open Cluster )is located in the constellation Perseus. M34 is 1,400 light years from Earth and contains around 100 stars.

M39 (Open Cluster) is located in the constellation Cygnus. The object is an estimated 800 Light Years from Earth.

M42 (The Great Orion Nebula) is the brightest diffuse nebula visible from Earth. Located on the sword of the constellation Orion, M42 is a favorite target for amateur and professional astronomers alike.

-For the amateur, M42 can make even the cheapest telescope look good.

-For the professional, M42 is one of the most active star-forming regions in the night sky.

@@ Weather permitting I will photograph the entire Orion Nebula some evening and post a special blog featuring M42's many treasures.

M45 (The Pleiades) is a prominent Fall and Winter open cluster that is located in the constellation Taurus. M45 is also called the "Seven Sisters" named for the seven hot blue-stars that dominate the cluster.

M31 (Andromeda Galaxy) is a favorite target of mine. Visible from early Fall to late Winter, this galaxy is a popular target of astronomers, because it is easy to find and is visible in even cheap, department store telescopes. Within proximity of M31 are M110 (looks like a bright-fuzzy star just left of M31) and M32 (faint galaxy to the lower-right of M31). You will see me include many pictures of M31 in my postings.

Hope you enjoy the images as much as I did taking them.
