Well, thats a rather awesome rendition Mike, but I cant see a fish, Lol.
Anywho, compared to other images recently, this is not as bright as, quess because of the selected signal you have chose to capture - with that said, your results show up very much betterra the low half of image where them bright spots of nebulosity patches are, & quite interestingly resolved which leave to ponder further on them !
Dig the colour palette also Mike, top show and grouse image
