LightRoom (white balance, color adjust, brighten foreground) -> Topaz Denoise (AMAZING!) -> Photoshop (remove unwanted objects in foreground, dodge/burn, curves adj) -> Lightroom (crop, exposure tweak)

On a whim decided to give it a go. Picked a well known sculpture park, intending to have a sculpture in the foreground. Those photos caught the comet but I did not take a "base" shot to get my foreground in focus, dang. This one turned out nice though, I was lucky to remember to frame it like this I was so excited to see it. I have several previous shots with only half the structure visible. Was not sure it would clear the horizon from my location, but it did. Could barely see with naked eye. Clouds rolled in and it was over about 15 minutes later for this night.
