Ive never ever seen such a deep image of this region. Many moons ago I read the Malin book "colours of the stars" where he showed a deep monochrome negative of it. But it wasnt so deep to show the galactic cirrus. This might well be the deepest ever image of the NGC 5128 area. Indeed the lobes from the black hole jet are easily seen. If it is possible to measure the surface brightness of the faint cirrus, or the lobes, I wonder what it would be? very very faint no doubt.
If youre looking to go this deep again, try the Chamelion Nebula complex, theres lots of integrated flux nebulae, dark and reflection nebula to be caught.
I think your imagery here is among the deepest ever seen. Some questions if I may
how did you power your scope? do they have 240V there?
Did you do 10 minute subs, or longer under the darker sky?
Thanks so much for sharing this amazing imagery
