There is no way a bi colour Ha/SII could be considered in any way true colour without it being a red mess but you could do a kinda standard HaSIISII (like with the HOO).
I'll keep that in mind once I get some S11 data. Clouded out tonight.

This was part of my PhD, I was lucky to get to spend some time using
a) A camera setup Mike Bessell arranged on the old 16" telescope at Siding Spring (from memory a large lens installed on the telescope mount) I took a heap of images for his project (a large area survey) also of the Gum Nebula and a few other things such as RCW114
b) UKST I was there for 5 or 6 months helping out with the H-alpha survey in the late 90s which was a heap of fun (looking for optical emission from suprnova remnants mainly). This paper was about from this time. RCW 114 on a survey film from the UKST is an incredible sight! A lot of the films and plates being made then were digitized with super cosmos (and maybe online somewhere?) but to be honest, the original leaved the digitised version well behind for quality and detail.

I think there may have been a few optical references in my paper, but there definitely have been a few in radio, Google Scholar will find the latest. Nothing I did was that ground breaking, but it's a real pleasure to see people still looking at these!

PS another object I looked at (I discovered the optical structure) was the Coalsack loop. This is another large object which also appears in radio emission. I made a few rough images with Mike's setup back in the day, but then recently I saw the images in this page, wow!!!

Wow, great to read your post Andrew. And thank you for your paper on this object.

I was unaware of the Coal Sack loop so I will definitely check that out also.
That was a good discovery.

Greg.
