Can't quite get Rosette Nebula how I want it


Recommended Posts

A month ago, I got some subs of the Rosette Nebula. There was a ton of light pollution from the Moon, which really bleached out the surrounding nebulosity, although the core was ok. Over the past week I've had another go at this, in perfect conditions - but still, I feel this is lacking something. When I look at other versions on Astrobin, using the same camera (examples here), they seem to capture more of the outlying areas which I thought my camera would do well, being Ha modded. So, does anyone have any recommendations here? Is there a particular module in StarTools that might help (I've had a few stabs at this)? Any cool tweaks in Photoshop or Affinity? Or is this really a case of needing more exposure time to get the outer nebulosity? Perhaps I should just try stacking the Moon-free subs and not try to incorporate everything? Any/all comments appreciated!

Other details:
• 5.8 hours of integration at ISO 800 (29*120s + 152*180s + 87*240s - different times because I'm still finding out how long I can guide for)
• Bortle 4 sky, moon 85% illumination for about half the exposure time, 0% for the other half
• Calibration: 25 flats, 25 dark flats, 50 darks
• Hardware: Sky-Watcher 130PDS scope (F5), Sky-Watcher NEQ6 mount, Canon EOS1000D astro-modded camera with Sky-Watcher 0.9x coma corrector, T7C guidescope (ASI120MC clone), Angel Eyes 50mm guidescope
• Software: polar alignment with SharpCap Pro, guiding with PHD2, capture with Astrophotography Tool (APT), stacking with Deep Sky Stacker (DSS), post-processing with StarTools, Photoshop CS2, Affinity Photo and Topaz Denoise AI
