Description

I've been through a few iterations of this image now, I absolutely love this target!

The original was the very first image I processed in PixInsight, stacked in APP.  I went back and had another stab at processing it 6 months later but discarded what I thought at the time was some dodgy luminance and opted instead for a synthetic L channel.  This year, I collected a further 15h of luminance and restacked the lot using WBPP - I think I'm now finally done and happy!
