Description

I took this as a comparison to the image I reprocessed from 2016. I added Ha to bring out the Ha knots in the arms of the galaxy. The moon definitely effected the detail not to mention that hurricane Michael did a number on the natural vegetation that provided some shielding from street lights, but any night of imaging is better than none. I will definitely need to add some shielding around my set up for future projects.
