Since this APOD is about processing...this might help....Processing is EVERYTHING....
Especially for me....most of my images are of short duration, I don't have the WEDGE for my scope, and a Field Derotator, and other equipment...so it has to be software supported. The result is not as much light is gathered...so I take more images to stack. I take 16 or so images, make an AVI file, put that in Registax, use that to align, and get the best of each photo into a single end image. Then take it to Photoshop. Using AutoLevel, AutoContrast, AutoColor. I have gotten some better results, a clearer image, and much brighter colors with an almost "back lit" look to them.
The bottom pic, is a little over done. Slightly blurred, but the colors are more vibrant. It was to see what my tablet APP could do...2. is the normal process, and really brought out the detail. 1 is very dingy, and hard to see, but smooth...so in 2 you can see background stars better. The bulges of M27 on both sides are more visible.
So, it depends on what you are after...better detail...more vibrant color...for Aesthetics, or Scientific data...processing can bring it out...So, for todays APOD, the processing is more vibrant than Margarita's second example. Which was probably the picture used for the processing as many features are in both...much sharper too...I am thinking the purpose was to bring out more structural detail.
