Description

Rev A - looking at data and now learning to process lrgb - I expect a few revisions as I learn. Not finding this target that easy!
Reprocessed with flatter images and tried to keep detail in the Iris this time
Rev C - Tweaked Iris colour as it was a little too warm.
Rev D - Removed overall reddish tinge and tamed stars a little
Rev E - lifted the dust a little
Rev F - Previous versions all felt a little pushed and un-natural so retried a full process.
Rev G - Tweaked the core a little so not so saturated - OK one more !!
Rev H - Lifted levels a little feedback welcome. Feel it shows the range of a little better.
