Thanks Trev,
Much appreciated
Even with a full moon illuminating the night sky , these Antlia 3nm filters perform really well. It’s the Oiii that’s mostly affected by skyglow and moon glare but I tried to capture that data when the moon was lowish.
Of course 12 hours of good narrowband data on a bright object makes for a high signal low noise image. I only had to use 2 pixels of final de noise, in fact I could have got away with no noise reduction it was that clean , and that’s under B8 skies.
Happy Chappy
Here’s a reprocess which has exposed a bit more faint detail
