Dark Tower (Scorpius) - challenging myself

Haven't seen this imaged very often, so I figured it must be a tough target. Wanted to push my gear, capabilities, and site conditions to the limit, so decided to give it a go.

By the way, does anyone know of a catalogue or ID for this thing? I've only seen it referred to as "Dark Tower", but no NGC/IC/RCW numbers etc.

Shot over the last couple of nights from home, inner Brisbane. Testing out the Astrodon 5nm Ha filter, I pushed subs out to 20mins each. I think the EQ6 with little finder guider handled it quite well. Probably not quite the ideal image scale, and would probably suit the 10" better, but just loving the little TMB92SS at the moment.

I will definitely try reprocessing this one. Might be a bit too saturated for some tastes, and the stars to be don't look saturated enough to me compared to the nebulosity. Think it's in my balancing of the Ha and RGB still.

It's just (HaR)GB, no Luminance. Ha was 10x20mins, RGB was 8x5mins each, so nearly 5.5 hours all up. Longest I've ever put into one image I think.

Any critique/comments/suggestions greatly appreciated.
