Well said, Mike. I had a couple of goes at responding but the words just wouldn't work for me. You captured some of what I wanted to say but couldn't wordsmith in my post (hence I left that bit out!

).
I'm a confessed "that's nice" feedbacker on a lot of astro images, too. If I feel I can add valid constructive criticism I will, but as a novice astro imager I don't feel confident to comment on colour balance of many astro images - because I just don't know. In the meantime, if I like an image I'll say so and offer encouragement. If I don't like an image, well I
won't say so unless I can say why and do it in a constructive way.
I appreciate the constructive criticism of everyone's images, not just my own, because I can learn from that too...
