Not at all keen on the colours of the first one so I'll talk about the second one only if that's ok as I have more experience in NB HST palette imaging.
Great use of the colour palette, bold punchy contrast and IMO it's the best rendition of the recent flight of Dragons published here.
You're a master of that GSO RC, you consistently produce amazing sharp images with it with perfect round stars from cnr to cnr and that in itself is no mean feat!
That said the only thing letting this otherwise very fine image down imo is the el cheapo ZWO NB filters. They have a bad rep for producing big bright haloes around the stars and this is really showing in your O3 regions.
Astrodon & Chroma NB filters are expensive for a good reason! (Chroma are now slightly better value)
Mike gets great results from his Astronomics, but I've yet to see decent results from ZWO.
Hope that's useful - overall very well done!
