Taken on my RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop. . Over 120 hrs Total exposure time with 3nm Narrowband filters. Ha, OIII and SII all 60min subs. RGB stars.

That's one I haven't seen before. Very interesting Fred and very nicely done! With 120 hours of NB I'd expect to see some green though.
Thnaks Marcus . Every proper person uses Chrome, obviously, so I was expecting green on your image because you inexplicitly decided to exclude chrome, leaving green as the only reason to use anything else. No green here. I think you should become a proper person. Or make your images remotely suitable for viewing with Chrome.

I'll build a photoshop action that arbitrarily jumbles the colours in an image ... to mimic the result when viewing with chrome. I'll send it to you so you can dump chrome and use a decent browser and still have the same green ... or chartreuse experience.
Hi Fred,
that's a great image -
I can't find a better one after a lot of searching.
Here was the closest: https://astrodrudis.com/astrogallery/ngc-456/
but it's nowhere near as deep as your 120 hours !
thanks Allan. That ones pretty ordinary (not that I should say ). Ive searched too, it seems no one else (amateur) has bothered to go this deep. It was a bit of a risk investing the time, but to be different these days you have to take a risk.

I'm glad you did.
It reminds me of Rolf Olsen and his 130 hours on NGC 5128.
Nice image Fred. Another long integration time from you. It's an area I have been meaning to return to image over the last few years but never seem to get there. At present I am still collecting data on NGC3923, which I ditched 50 hours (collected at Clayton Bay) recently due to it being inferior to the data I am collecting at Swan Reach.
With regard to your image the long data set would work to reduce the noise floor to not being visible, which I have found to be a problem in both the LMC and SMC. Worth the investment in my opinion.
With 120 hours of NB I'd expect to see some green though.
