Nothing else seems to pick up those faint halos so well.
Is it Rolf Olsen who pioneered that?
NGC5128 with NASA data added showed us the way:

Rolf is a legend and yes I think his 120hr Cen A, completed back in mid 2013, illustrated the effectiveness of uber long exposures and may well have started the trend...now, some ten years on, there are whole groups of imagers combining efforts to compile amazing 200hr, 300hr+ exposures

, that are revealing vanishingly faint features and have made numerous discoveries, it's almost a kind of magic

Eventually there will be more of these collaborations and much, or all, of the sky will likely have been imaged in this manner..?
At 27.5hrs, my M83 is a mere token effort in comparison...but still, I'm happy with the outcome, my location helps
Mike
