Another wonderful image Greg !
Excellent work and the scope is certainly delivering fantastic data.
You're also doing a great job in processing that data and I agree that it's a personal preference in the end how much colour is in the final image.
renormalised is correct in that if we were to process to what the eye sees it would be a "dull greyish blue-green" but that's not why we image these objects for such long exposures.
Well done once again.
