The following images were taken on 28 Jan 11.
It has been a long time here in Zuni when the weather cooporated with us so that we have been able to get out.  This evening we concentrated on nebulas in the Orion constellation or those close to it.  It was one of the best evenings we have had since we started.  Pls compare our past M42 images.  As you can see it has improved some. .  In fact, we would like you to go to Science Magazine and see the image from the La Silla Observatory, Chile and compare them.  Keep in mind that their telescope is over 78 inches and in the mountains, ours is an 8 inch telescope.

M42
The Great Orion Nebula 

Is considered a diffused nebula and on a dark night is visible to the naked eye.  I don't know how naked the eye has to be but I sure have not seen it! It is only 1,344 light years away, and roughly 24 light years across.  As you can see, it has turbulant and intense motions in the gas.  There is a young open cluster, known as the Trapenzium, primarly four stars - there two addional stars not quite as bright that make up this cluster . Nicolas-Claude Fabri de Periresc in 1610.  This image is a stack of 40, at 15 sec. using the equipment on the index page.

Part of the 'Running Man' is located to the upper right side of the image.  Will have to capture this one another time.

Barnard 33
The Horsehead Nebula

The Horsehead Nebula is but a part of the optical nebula IC 434, sometimes known as the Orion Molecular Cloud Complex, (try saying that 5 times quickly) some know it as Barnard 33.  The nebula was first recorded on a photographic plate in 1888 at Harvard College Observatory by Williamina Fleming.  Its profile makes it one of the most familiar of astronomical objects.  It is a dark nebula with an extremely dense cloud in front of ionized hydrogen gas.  This gas is ionized courtesy of Alnitak (the bright star to the left). The nebula is approx 1500 light years from Earth. 

NGC2024
Flame Nebula

Looks are deceiving; the nebula is some 1300 to 1600 light years away from earth, while the star Alnitak is ‘only’ 815 light years away.  While much of the billowing fire from the nebula is from ultraviolet light having electrons knocked away from the clouds of hydrogen our nebula glows when the electrons and ionized hydrogen recombine.  The dark areas are the result of gas and dust in front of the nebula.  Gives a new meaning to the term ‘what a gas’ doesn’t it?  This is a star forming region.


Beehive Cluster
M44
The Beehive Cluster is one of the nearest open clusters to our Solar System. It was one of the first objects that Gallileo studied it with his telescope.  This cluster contains red giants and white dwarfs, which represent later stages of stellar evolution,along with main sequence stars of spectral classes A,F,G,K and M.  There is no consensus on the cluster's distance, from 520-610 light years, and approximately 600 million years old.  
While not part of the Orion complex, we have it here to honor our bee hives at school.
M43
Running Man
Just a little north of M42, is the Running Man Nebula, you can see just a little of it in the  resemble its namesake.  You will notice in between the two nebulas is an area of brown dust.  

M78
Reflection nebula
Not far from both M42 & M43 is M78, indeed it is considered part of the Orion molecular couud complex.  I need to warn you all this this just a preleminary image.  We have determined that we need to reshoot this nebula with additional images in order to bring out the clouds of gas and dust..  We think we can do better but until then this is a good beginning.  
NGC2244
Combo
Star Cluster & Rosette Nebula
This is a younge star cluster only some 4 million years old.  Since they formed they are pushing the gas and dust from the Rosette Nebula away, hence the clear 'hole'.  They are in the constellation Monoceros, not far from the Orion complex.  
The name Rosette comes naturaly from the the shape of this nebula, that of rose petals.  Some 4,900 light years from earth, they are considerably farther away from earth than M42 - almost 3 times as far!  
We chose to bring out the different colors of red that this nebula has.  Enjoy! 
NGC 1788
Reflection nebula
In the Orion nebula complex, and an area not often imaged. It is a good example of a reflection nebula.  We hope to increase our images on this nebula as well, until we do, you will get an idea about this one.

NGC 2264
Cone Nebula
In the constellation Monoceros and is located about 2600 light years from earth.  The Cone Nebula is part of the Christmas Tree Cluster.  Unfortunately, we captured just a sliver of the cone on the upper right side.  The bright star you see in the center is S Monocerotis and is the brightest in NGC 2264.  This image is a result of 150 - 15 second images stacked together.  Next time we will try and get the actual 'cone'.  In any case, this star-forming complex has many beautiful components.
