This is a combination of 50 minutes of each LRGB in 10 minute subs. I actually captured another set of frames like this after a meridian flip but have no idea what went wrong with them. When processed up they give what appears to be a huge greenish halo around the Rose.
I recall Paul Haese posting a similar result on an image he did of lagoon nebula some time back. I ended up only using the images I captured before the flip which have given a hlaf way decent image.
