Not one of my best images, as it was low in the sky and creeping into the London LP, will be so glad to get back to Cairds for some darker skies. 

Tried taking Oiii and Sii, and there was virtually no Oiii (I guess there might be with better skies), so I added the Sii to the blue channel.  So this is HaRGSiiB, so although I took at least another hour of this the presented results are just over 4 hours.

Not much in the green channel though as that one kept catching the clouds.

3 hours Ha (Baader 3.5nm)
30mins Sii (binned 8nm)
35m RGB binned totalling, just over 4 hours.

I think that's pretty good given the conditions.  You've captured the subtle variations in colour that often go missed.
