I managed to get the final colour data for this one so this image consists of 13 hours of Ha and 6.5 hours RGB. There is plenty of interference from Alnitak which I attempted to minimize a bit. The final image doesn't look too bad to me but feel free to criticize as it's the only way I'll learn.
Cheers
