Hi Mike and Trish,
Although Don managed to capture more detail, his interpretation is way too red for me; I like how you balanced the colours. I think this target might be a good candidate for an ongoing project- maybe you could add more data one day/night and see if that helps to bring up the faintest bits even more?
Having said that, I think it is a fabulous image of a very difficult target - I do not even think of imaging objects past magnitude 10
