Messier 47

The open cluster M47 is approximately 1600 light-years from Earth and is 78 million years old.

NGC 2264, Christmas Tree Cluster

Here is the Christmas Tree Cluster (the bright star forms the base of the trunk) and the brighter portion of the Cone Nebula. Much more exists in the IR spectrum. This would be a good subject for a CCD or modified DSLR.

Messier 36, another revisit

Another improved image, unguided, 117 x 15 sec JPEG frames (threw out 50 frames because I just couldn't get the neighbors Christmas light glow out...they were on a timer, and shut off about an hour later), 1600 ASA, noise reduction enabled.

M42 Orion Nebula, revisited

One year ago, I made my first telescope purchase in years, a 6" inch Newtonian and an Atlas mount. Bought a DSLR camera, too. I desired to learn about digital astrophotography. As the year progressed, I found myself in a relentless pursuit of simplicity. I could have taken the high road and gone with much more expensive CCD technology and computer-based control and processing, but it just did not seem worth the expense.

Taking an approach similar to radio astronomy, short samples at high gain, has been as rewarding as I could have ever wanted. Without so much emphasis on technology, I find I'm enjoying my study of the heavens, telescopes, and astronomy just as much as I did in high school.

So in tribute, here is an unguided retake of Orion nebula, one year later.
