Think i have the handle on flat frames now, so this is my first real attempt, well after M42 anyway, taken last night, 12*10 mins subs on QHY8 OSC, with flats, post-processed in Nebulosity, then juggled with for ages in CS4.
I tried to take some shorter shots to blend into the core, but i fudged it, never mind! its not that bad an image to share anyway, even if the core is a bit burned.
