Three Diverse Sights

C31 - Flaming Star Nebula

M81 & M82

NGC 2264 - Christmas Tree Cluster & Cone Nebula

The first two photos above were shot at my dark sky site. A gorgeously clear, but very cold, night.  We began imaging at 24F (7 PM) and finished up at 21F around 11 PM.  The last one was shot from home and suffered from a lot of light pollution.  It would be fun to try again from a dark sight.

The flaming start nebula (C31) is a very large emission/reflection nebula.  This was one of those photos I took on pure faith.  A few marker stars that told me I was on target, but I couldn't see any of the nebulosity until I got into post-processing.

M81 & 82 are a beautiful pair of galaxies about 11.5 million light years away.  Messier 81 is the face on galaxy and has the classic "grand design" structure.  Messier 82 is the smaller of the two and is known as a star-burst galaxy.  Interestingly, the two interact with each other and the active star formation going on in M82 has resulted from interactions with M81.  Near the core of of M81 there are more stars being formed than in all of our Milky Way.

The last photo is the Christmas Tree Cluster and the Cone Nebula.  The Christmas Tree is plain to see, but the nebulosity is much tougher.  Again, one of the photos I took on faith.  The cone nebula is near the top of the tree and points downward toward the tree.

Rosette Nebula


The Rosette Nebula is one of the most stunning heavenly sights, but nearly impossible to see visually through a telescope.  It is known as an emission nebula with active star formation in the center.  This star formation heats the surrounding gas to 6 million kelvins generates vast amounts of x-rays in addition to the light we see in this image.  Simply stunning!

Pristine Sky

Horsehead & Flame Nebulae

Flame Nebula 

Moon

Messier 77

On the night of January 3, we had extremely good conditions and I was able to meet up with a fellow astrophotographer at my dark sky site for a great imaging session.

The Horsehead and Flame Nebulae, to me, are absolutely stunning, but are a good lesson in patience.  Each had over an hour of exposure time and I had to work extremely hard to tease out the details.  It will be fun to go back and attempt these targets again with more time.

The moon was gorgeous as well with just a sliver visible as we were setting up and it set around 7:45 pm.  I don't often get to photograph the moon this early in the cycle, which made it especially fun to capture.  

The last photo, M77, is another galaxy in the Messier list.  I definitely need to use more magnification in the future on this one!
