Thanks a lot Simon, glad you were impressed
Cam, there is a surprising amount of nebulosity in the area that can be teased out with H-alpha. I exposed in Ha for a bit more than 2 hours. When stretching the image, I could see a lot more, but didn't have the SNR to pull it out cleanly, so only left the brightest part. I reckon with 5-10 hours exposure in this area on Ha, one could draw out some fascinating extra nebulosity - which really complements the cluster.
