Thanks Mike, Dave, Rick & Ross.
I spent a fair bit of timing thinking about the best composition, so I'm glad you liked that. It's actually a challenging target, because the Ha emission nebula is difficult to draw out without overstretching the background Milky Way stars (too much and the background degrades into a graininess). I might not have got it quite right, but I'm pretty happy overall with the result.
It can look like quite a different object if one just concentrates on the cluster stars and ignores the nebula - the background gets much darker, but the traceries of gas is then lost.
