Morning Moon

Here are some pictures of the waning Moon taken one morning with the EOS Rebel T3 and the 18-55mm zoom lens.

Rising Moon

You know those really cool pictures people take of the Moon rising behind interesting objects? I've been wanting to do something like that for a while, so I decided to go out and catch some shots of the rising moon from my front yard. The images are nothing spectacular, but there is something special about the Moon when it's low on the horizon...

I also took some quick shots of the Flame and Horsehead Nebulae in Orion while waiting for the Moon to rise. This image is composed from 7 30-second exposures at ISO-6400, and minimally processed in GIMP.

And before the Moon got too bright, I took a few shots of the Double Cluster in Perseus. This is from 12 30-second exposures at ISO-6400, and minimally processed in GIMP.

2013 Parting Shots

Between the weather and various projects, I haven't had a lot of time to dedicate to astronomy recently. I did, however, set aside a few hours during some near-perfect conditions one night over the Christmas break. It turned out to be one of those rare sessions when nearly everything went perfectly--setup went quickly and smoothly, alignment was good, I found the targets quickly, and the images came out better than I expected.

This first image is of the Heart Nebula, IC 1805, located in the constellation Cassiopeia. This is a large and difficult target for my equipment. I was surprised that it turned out as well as it did. The brighter part in the lower-right corner is cataloged as NGC 896. It was discovered before the rest of the nebula. (The Index Catalog is an extension to the New General Catalog of Nebulae and Clusters of Stars, and contains many objects that were too dim to see when the NGC was made.)

This is the Monkey Head Nebula (NGC 2174), located in Orion. It surrounds open cluster NGC 2175. I don't see this object being imaged very often, so I figured that it would be fairly difficult to pick up on the camera. It was surprisingly bright, though. I really like the contrast between the red emission and white reflection regions.
