The Cat's Paw has a paw-city of OIII and SII, making it tricky to produce a Hubble Palette version.
Here we've added 9.5 hrs of SII and 8.5 hrs of OIII to just 2 hrs of H-alpha.
Total exposure is 22 hrs, of which 7 hrs was from 2014 in half hour subs, and 15 hrs from the last two nights, all in 1 hr subs.
The OIII was added under somewhat non-ideal conditions with a half moon shining right down the barrel and trying to climb inside the scope. Thus the very faintest blue-black washes are to be ignored, but the middling and brightest blues and localized blue detail should be solid. The little patch of inky blue at the left hand edge toward 10 o'clock should be real, and seems unrelated to the main paw.
A very busy image, with at least 5 discrete and idiosyncratic regions. We can see that the cat has been walking around the kitchen as well as the fish pond. Dead centre is the "thorn" in the cat's paw, or perhaps a shark's fin. Toward 5 o'clock is a roast chicken with burned crispy skin and an alarming blueberry sauce. Toward 12 o'clock is something like a giant electric eel with a black eye and huge sharp teeth, trying to bite the tasty morsel toward 9 or 10 o'clock from centre. All these regions have very different textures, implying different dynamic causes.
The big one is here
