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.

First Light with the Orion (Celestron) 9.25" SCT

First Light with the Orion 9.25" Schmidt Cassegrain Telescope (made by Celestron) actually occured a week ago at the Northern Virginia Astronomy Club - Star Gaze 2008.

That night, I did not take any astro pictures, but instead enjoyed looking at deep space and solar system objects with my new telescope tube.

The views were beyond my expectations, and better than anything I have owned before.

First Light was on Jupiter as twilight gave way to night. The atmospheric bands were clearly visible, but alaas the Great Red Spot was on the other side of the planet. Other objects that I viewed were M8&M20, M16, M17, M31, M32, NGC869&NGC884 (Double Cluster), M11 and of course, the Moon.

The most spectacular sight was M11 (The Wild Duck Cluster). I had a Baader Hyperion 17mm eyepiece attached at the time, and many attendees could not believe the clarity of the stars, and even saw deep into the clusters center. They felt like they were walking in space.

On Saturday, Octover 11th I finally had a chance to test the Orion 9.25" SCT's astrophotography abilities. I was dealing with a near-full Moon and haze in the sky, along with some dew on the corrector lens, so the pictures aren't the greatest. Also, I only took 30-second shots, which do not bring out faint deep-space objects.

Below, are a few shots that I took. (Click on the pictures for a larger image)

This has to be the most crisp Moon picture I have ever taken.

NGC869 is one of two star clusters visible in what is called the Double Cluster. This was a 30-second shot. An exposure of 1 - 2 minutes would reveal several more faint stars.



NGC884 is the other star cluster visible in the Double Cluster.




The last picture is of one of my favorite space objects: The Andromeda Galaxy. This galaxy is our closest neighbor and is made up of three galaxies. The bright main galaxy, M31 is at-left, M110, a small galaxy is a faint object 1inch to the left of M31. M32 is a small galaxy on the right-side of the picture. A longer exposure on a moonless night will reveal much more detail on all three galaxies. The hazy granular texture on M31 is caused by dew forming on the corrector lens.




As time permits, I will take additional pictures with my old and new telescope and add them to this Blog.

Clear Skies!

Out With The Old, and In With ...

Hi All!

Here are a few photos to round out the year. I've been busy the entire month and haven’t been able to write any BLOG entries.

My star gazing opportunities have been few and far between because of cloudy nights.

Photo 1 is Comet Holmes taken December 14th with a jet flying through my field of view while I was taking the shot.

Photo 2 is the Constellation Perseus portion of the Milky Way Galaxy. The star field is very dense in this portion of the sky. You can see Comet Holmes in the upper-right portion of the picture.

Photo 3 is M42 "The Great Orion Nebula". The Pinkish-Purple colors are the actual colors of the nebula. Some photographers doctor the colors, but you'll not see that with my pictures. I believe in showing what can be seen with the naked eye through a telescope or binoculars.

Photo 4 is M31 "The Andromeda Galaxy. It's our closest neighboring galaxy. The fuzzy spot just below Andromeda is M32, and just above Andromeda is M110, two dwarf galaxies.

Photo 5 is uhmmm ... Mars. It's the best I could do with a shaky camera tripod. I got a new camera tripod for Christmas, but haven't had a chance to use it yet.

That's it for this entry. I've been studying visible constellations for this time of year and am planning some star gazing sessions to locate new (to me) galaxies and other deep space objects.

See you in 2008!
