What a treat it was to work with this data! Additionally, what a treat it is to use the full set of tools available in PI (or at least the ones I've figured out!)
The real challenge working with this data was how to combine the narrowband. The SII signal was very strong, but I am partial to the HOO version of this target, as it more closely reflects the natural colour visible in broadband images. I didn't want to completely throw out the SII data, though, so I tried to find a way that it could add a little dimensionality to the nebula. This went through so many different revisions that I no longer recall the exact pixelmath, but it was heavily influenced by the
excellent article by
The Coldest Nights (thank you!)
The RASC Robotic Telescope imaging team collected nearly 30 hours of narrowband data, and 45 minutes of RGB stars in May & July of 2020. Many thanks for the excellent data & careful acquisition!
