Hey cheers guys, glad you like it
David, it is similar to the multi layered decon technique many use for detail extraction ie basically careful use of DDP and high pass in Astroart5, shadow highlights and curves in PS and careful blending of several slight variations. With Omega one needs to be mindfull that it isn't symetrically round and in-attention to this will result in an unantural appearence. 47 Tuc is much more symetrical so a little more forgiving.
The AG12 data was seeing affected actually which would usually be a negative thing but here it actually helped acheive the overall look I was after actually - funny how things can go in processing...really is like cooking sometimes, bit of this, taste, bit of that, taste...voila
