Canon 7D Mark II, Canon 300mm f2.8isII + 1.4xTC III, f4, 25 second exposures, ISO 1600, Sky-Watcher, 62 Subs (25.8 minutes total exposure), No Darks, Flats, or Bias Frames Taken. PixInsight, Photoshop, Lightroom.
Please View In Shadowbox. I began shooting the night sky in January of this year, and the frames used for this image were shot on January 20th. It was my 3rd night out with the new equipment and I remember it was bitterly cold. I posted this image back then after processing it with Photoshop (manually aligning and averaging the images) and lightroom. At the time I was amazed with the details and the colors, however I had no idea what the colors were supposed to be, or the contrast, or anything really. The result was artistic, but I had no idea if it was true or not. (Image posted below for comparison) Since then I have spent many hours studying the processing of astrophotography images. Working with these files is a unique and challenging process as shooting in the dark yields a very low signal and only through the combination of many images and tactful extraction of that signal do the details begin to emerge. A few months ago I added ImagesPlus to my workflow. It is a capable editing program, but not one that I could figure out despite researching the tutorials available, so I used it to stack images and then switched to photoshop and lightroom for stretch and fine tuning. This workflow improved the quality of my images, however I was still largely unfulfilled with the final product. A few days ago I downloaded a trial version of PixInsight, one of the most complex but capable photo editing software platforms ever created... and targeted specifically at astrophotography. After many hours of learning the program I dove in and began editing old image files. At first I started with my most recent, which I was sure the data was better, but as details in these images began to emerge that I did not believe were there, I started to re-visit my older data, from the first nights out. This rendition of The Orion Nebula Complex and Running Man was created with the editing tools of PixInsight, and while I am just barely beginning to scratch the surface with this complex program it is quickly becoming clear to me that it is extremely capable at unlocking the data hidden within.
