This was a double page image that netted me about $12,000 ($20,400 in 2023). I guess that changed my status from amateur to professional. Heh heh.

This image shows what PixInsight's Dynamic Background Extractor does to an image. The amazing detail is brought out by balancing the background light such as caused by light pollution or breaking dawn in this case. Using a RAW file is essential and the more stacked images used helps to reduce noise. The orange streak at bottom is some high cirrus clouds hugging the horizon.

It took me about 4 hours to post-process this image. Because of bad tracking and atmospheric turbulence, I rejected at least one-third of my images. I selected only ones where stars were bright and round. My camera (DSLR DX) and lens have a resolution of about Pixel scale: 4.474 arcsec/pixel. Most telescopes have a resolution of 0.5 to 2 arcsec/pixel with their CCD imaging.

This is another one of those photos that I just had to improve. Here is the original: www.flickr.com/photos/79387036@N07/27026180654/in/album-7...
This Higher Tonal Contrast version, while looking perhaps a bit exaggerated, does create a dramatic touch that wasn't too far from what I actually witnessed. I also de-saturated the scene a bit.
