Thanks very much.

Very dramatic

Quite an interesting look at a familiar object

I love the colours

I didn’t have S2 component and I really don’t like this combination where R=S2, B=O3 and G=Ha. It’s as unnatural as (almost) possible.
So, having “strong” RGB frames I added O3 to G, Ha to R and a mixture of Ha+O3 to L.
