Since my first session imaging the Orion Nebula back on January 28th was out of focus, I decided to learn more about how to focus my CCD camera. I wrote about my experience learning how to focus in an article entitled, The Importance of Focusing When Imaging Deep Sky Objects.
As I read up on the topic and got more helpful hints from my mentor, Michael Caligiuri, I gave imaging M42 another shot tonight. Again, I set out to capture 24, 5 minute exposures of the magnificent Orion Nebula but my guidescope came out of alignment and I ended up with 8 salvageable images, which I then processed into the image you see below. I am much happier with this latest image of M42 as it seems to be in focus, which reveals much more detail than the image I took a couple days ago.
