M74
Galaxy
A Pisces galaxy, M74 is considered by many as one of the hardest galaxies to image as you can see we've caught the dude.  Even though it is listed as M74 it was discovered by Mechain in Sept 1780.  This beauty is approx 32 million light years from earth and some 97,000 light years across.

M42
Orion Nebula
   As you know this is an image of the nebula on our index page.  I wanted to publish this graphic because it represents just two images taken with our CPC Cellestron and our HyperStar.  We captured just the two before the power died on our computer.  Image taken 7 Dec 2010
M27
Dumbell Nebula
This planetary nebula is one of the brightest in the sky and can be seen in the constellation Vulpecula with binoculars.  It takes approx 1000 years for light to reach us from M27.  This has to be one of my favorates.
M57
Ring Nebula
This planetary nebula is approx 2,300 light years from earth .  It has a visual magnitude of 8.8.  There is a a central white dwarf at the center that lights up this nebula.  The ring nebula is known as bipolar, not because it has good or bad days but  because the thick equatorial rings visibly extend the structure through its main axis of symmetry.  

M104

The Sombrero
Galaxy It has a bright nucleus, an unusally large central bulge.  The dark dust lane and bulge give this galaxy the appearance of a sombrero. The large bulge, central supermassive black hole, and dust lane all attract the attention of professional astronomers, the rest of us are attracted by its beauty.   It is approx 23 million light years from earth and is located in the constellation Virgo.
M71
Gobular Cluster

Discovered by Philippe Loys de Cheseaux in 1746 and researched by Charles Messier then added his catalog of comet-like objects in 1780, this brilliant globular cluster let’s its presence be known at a distance of about 12,000 light years away from Earth. Covering an area measuring approximately 27 light years across, it shines with a luminosity of around 13,200 suns – not bad for a conglomeration of stars which could be as old as 9-10 billion years.  Our 8 inch CPC does not do this cluster justice, the images by NASA really bring out the beauty of these guys.

M-18
NGC 6613
Open Cluster
This cluster is about 4,900 light years away from earth and approx 17 light years across. The hottest stars in M18 are type B3 and quite young estimated at being approx 32 million years old.  This cluster has a good collection of bright blue, yellow and/or orange stars.  Located between M17, the Omega Nebula and star cloud M24.



M67
Open Star Cluster

 M67, is 2,800 light-years from Earth, so the light you see from its stars tonight was already en route to us when the Greek philosopher Plato was born. Because of M67's age, astronomers often observe its stars to study stars as old as the Sun.
