Description

Hello everyone for the 3rd time this week.
The skies have been kind the last few nights so at the expense of any REM sleep, I've been up working hard to gather as much data as possible. Here is the second of my "return to" images where I take a new pass at objects I've previously imaged but with better equipment and more "know how". M33 has such a low surface brightness under light polluted skies that I really had to take a more aggressive approach to my post processing. It came at the cost of overall smoothness. However, I am still pleased enough with the results to post it, especially how challenging this target can be. Thanks for stopping by!
