Wow, I'm absolutely over the moon to hear that feedback from people like you all. Really made my week!
I've doubled that time on the target, and while it seem to be subtle, I think the outcome is good.
Integration now sits at 102 x 240s Oiii, 60 x 240s each Sii and Ha, almost 15hours.
Have marked it final in astrobin, though I don't know if I can/will stop there.
