Description

Here's my take on Orion.  I shot this with the intention of bringing out Barnard's Loop while capturing most of the other stellar gems the great hunter possesses.    This was also my first use of my Canon EOS Ra with the Canon EF24-70 F-2.8L ii USM lens.  My goal was to capture the entire Orion asterism and expose long enough to bring out Barnard's Loop.  Initially, I thought that my zoom setting was too wide (80mm FL) as I also wanted to get some of the other treasures laced throughout the asterism.  As a result,the stars near the edges were extremely elongated.  As I didn't have a field flattener for this set up, I ended up cropping out a good portion of the surrounding area.  Lucky that I had the room to do this without cutting out the detail.  I was able to save and bring out the witch head nebula in the lower right corner.  My other challenge was to try and reduce the overwhelming number of stars in this region.  After successfully using the StarXterminator  (by RC-Astro) process I was able to reduce the stars effectively.  I reached a roadblock as I don't know how to recombine the images.  I'm not yet familiar with Pixel Math, so if anyone knows how to do this, please share you experience.  In the long run, I used the star reduction process in PI and It did well; although some artifacts remain of the reduced stars if the image is zoomed in. I'll try using Star Mask next time and see what result that yields.   I shot this image at a dark sky spot just north of Camp Verde, Arizona. Overall, a fun project and worth enduring the cold weather.  As always, comments, criticisms, and suggestions are most welcomed.  Enjoy and thanks for looking in!
