Yaaay! Rolf is back, Rolf is back
Lovely image! The complex halo structure is so cool on this one and you have managed to show both it and the core detail very nicely
I like your composition too...but is that the full frame? I ask, as you have missed a lovely faint but large looped tidal extension that extends off the top left of the galaxy in your image there.
Nice to see you doing another (closer to) normal exposure time image too...just so us mere mortals don't feel so lazy and bad
Oh and the noise you speak of is a non issue as far as I am concerned, the majesty of your capture far surpasses the irrelevant noise.
