Description

This image consists of around 2 hours of RGB data on M8 and M20, taken from my backyard in Austin, Texas. The first processing of the image I tried to dim the the glow of all that dust in the milkyway, to highlight the objects I was focused on. I then reprocessed the image a few months later and let the dust stretch with the main parts of the image, and I have to say I like it a lot better.
