12hours worth of narrowband Ha, OIII, SII taken over two nights. Stacked as separate channels in APP and then processed in Startool 1.7 using SHO proportions of 40SII+60Ha, 70Ha+30OII, 100OIII. Final tweaks in Photoshop CC.
Warming nicely to my new ASI294MM plus Antlia narrowband filters. This is a much more enjoyable subject in narrowband mono.
My earlier attempts with OSC came out perversely as pretty mono-chromatic. To be able to pull such blues and orange/green tinges I think makes this a much more interesting target... and to my eyes at least looks like it's aflame :-)
