Description

I love this nebula. Looks just like my little Dog's paw print hence my adjusted title. As noted I'm not much of a cat person so indulge me :-)

Just over 16 hours of integration taken over 4 nights (cant image this one till after say 11ish).

Stacked and combined in APP mapping Ha, OIII, and SII in SHO and adding both OIII and SII as 80% green.

Then separately processed and combined the Ha OIII and SII layers in startools also in SHO.

I liked the detail from Startools and Stars and colour from APP... so tried something new where I then aligned the results from APP and Startools and adjusted opacity till I got a compromise I liked.
