Nice one Greg! (although I'm assuming NGC4945
)
Looks like you've picked up some really really deep data, especially in the Ha - but I'm not sure what's going on there seems (at least on my screen) a weird noise profile over the image, even on the large version
. I'm assuming it could be something with the processing rather than the data, but it's obscuring some of the detail. Anyways - feel free to disagree, but i reckon another run at the processing could bring an absolutely cracking result!
