The Dark Shark, revisited

[tomato]

Very frustrating weather at the moment, some clear spells but enough frequent passing cloud to make an unattended extended imaging session very difficult. So looking through the archive I found two sessions on the Dark Shark, a short one taken from a dark site at the Autumn Star camp at Cwmdu, and a longer session from my own back yard, all with the RASA8/IMX 571 OSC. 7.7 hrs in total, processed primarily with the X-suite of tools in PI.

This may be an artefact of my processing, but there appear to be three distinct wave fronts along the dorsal of the Shark, highlighted by the blue emission nebulosity but also visible lower down, and on his underbelly there are some features that closely resemble the Ghost Nebula (Sh2-136, VdB 141), presumably the same process that created those spectres is going on here?

Superb image. To me a touch magenta overall ? Please delete my attempt.

Very nice Steve... swimming the wrong way though  .. as Francis says it does look a bit magenta..  sometrimes this can be caused by running scnr or equivalent prior to colour noise reduction

Thanks for the feedback, hopefully this one has the reduced magenta.

And why is Bruce this way up? In homage to my favourite movie and the iconic poster:😁
