Ah the good'ol Lobster....
It's a fabulous area the inner area of NGC6357, like a maelstrom
. and you have reflected this nicely. I like your colour palette too, showing some variation in colours to reflect that
three filters were used not just two
Main negative is, that when viewed at fit-to-screen it looks o-k... but any larger and there are a lot of processing artefacts visible
Overall though, a cool bit of neb
