As you can see the stars get in the way to see the dim stuff clearly.
With this detail the Vela Supernova Remnant looks eerily like the Crab Nebula.
Crab Nebula. Distance 6500 light-years and about 6 light-years across. 1000 years old. Hubble image is 6 arc seconds wide.
VSNR. Distance about 800 light-years and about 100 light-years across. 11000 years old. My image is 6.1 x 3.4 degrees and there is more of the SNR outside even this FoV.
Your star rejection workflow still leaves artefacts, I haven't found one that I like, some work OK for some images, but not for others. But like you have said, some of the fine detail is hidden by the multitude of stars.
I had a play with your data, hopefully it looks alright. To reduce the stars I used star tightening in Nebulosity, it seems to work well. Thanks for letting people use your data, it's great for trying out different processing techniques that I wouldn't otherwise be able to with my own.

I have a not so secret weapon Stuart. It is an Astrodon 5nm Continuity Filter that collects NB near HA and NII and only records stars, as its wavelength is outside any nebular emissions. This data can then be used to subtract stars and haloes with surgical precision. I hope!

My system has cost in excess of $70k. I would be a fool to keep it all to myself. The data it generates is not much good in a dark drawer or worse limited by my own abilities. It is a fundamental pillar of scientific endeavour for free and frank exchange of data or information. If someone can learn from playing with my data that is a very good thing. It is even better if they can do better than me, then I may learn something.
Before I retired my job was to maintain and improve and then collect data with three million dollars worth of x-ray crystallography equipment for CSIRO.
