Mmm - I'm not into imaging, I'm into visual astronomy
Still, I look at many of the images posted to see what's in them - as to their quality I do not think I am in a position to comment since I barely know what it involves, other than endless patience and miles of wiring...
In short - if a discussion arises regarding an image's contents, I may reply... most of the time though it seems the discussion focuses on the quality of the image, to which I feel I have little if anything to contribute
