Colourful Christmas Crab

[Jon]

I finally "finished" my narrowband capture of M1, the Crab Nebula in Taurus. 2.5 hours of Hydrogen alpha, 2 hours of Oxygen III, and 3.5 hours of Sulfur II.

Now the problem is what to do with them! Here are three combinations:

1) the "standard" Hubble palette with Sulfur as red, Hydrogen as green, and Oxygen as blue.Very interesting - that supernova sure flung a bit of mess around, elementally speaking!
2) a "true colour" narrowband, if that's not a contradiction in terms: OII blended as a greeny-blue; Hydrogen blended as lighter red and a bit of blue (assuming there's Ha and Hb in about the same places); and SII blended as a deeper red.
3) a greyscale luminance.

What I might end up doing is getting some normal RGB and using the narrrowband simply as a luminance channel.

Some fine details in there Jon, nice job, I think I prefer the more colourful version :question:...getting some RGB and using the NB data as Lum might work too.

Fine capture, and nice round stars to go with it.

Personally the stronger colour images look more pleasing to me, but then colour in deep sky is a personal thing anyhow.
