Description

This is M42, aka the Great Orion Nebula. This image was created using a combination of 2, 5, 15, 30, 60, 120, 300, and 600 second exposure sets. The images for each exposure duration were calibrated, aligned, and stacked in Maxim DL. They were then brought into Photoshop CS3 where they were iteratively layer-masked to reveal only the non-over-exposed areas in each image. I guess you can call it the "manual HDR" technique. I then brought it over to Pixinsight for additional HDR processing as well as noise reduction, dark structure enhancement, and color saturation.
