Hi Steve,
Thanks for the good news.
Regarding the sulphur channel, I'm afraid I beg to differ. So do you keep the stash under the floor boards?
I spent many hours researching this, the majority in astrobin. What struck me was that the images that appealed most, nearly all had s2 data. I felt that this gives a slightly wider palette.
I'm a fan of Astro anarchy, J P Metsavainio who also used the full hubble palette in an early APOD in 2009. My main source was Astrobin.
I just revisited that site and here are a few authors to help finding examples, should you wish to check them out.

This is purely FYI as a counter to what you said. I think the price of gold is quite high right now.
Really looking forward to more Ha. I used blink to carefully go through all the narrowband images, and found that only those taken, I think, on January 15th around 8 pm were worth using. Just 10 of those gave what I consider a pretty good result. For me quality over quantity.
Cheers,
Ray
