Comparison of stacked images of the Orion Nebula using Deep Sky Stacker and Nebulosity
I took the same set of images and stacked them in DSS and in Nebulosity. There were some star registration problems due to mount alignment, but the clear winner in terms of optimizing this imperfect alignment is Nebulosity. Here are the images:
The first image was stacked in Nebulosity. The second (below) was stacked in DSS:
The difference in image color is due to the color "normalization" algorithm in the auto adjust for Nebulosity and Photoshop.
