Mixed results with my wide narrowband imaging. I can definitely see all the structures I expect, but whilst the oxygen data (blue and green channels) is in perfect focus, the hydrogen data (red channel) is a blurry mess. Not sure if that is because of chromatic aberration and/or lens back focus or because of internal reflections.

Still, it is what it is. And it is this: the Vela Supernova Remnant and Gum Nebula(e), the Southern Milky Way from Crux, via Lambda Centauri to Eta Carina, and the center of the Milky Way in Sagittarius with Lagoon, Trifid, Eagle, Swan and Star Cloud.

All these are 24 x 300 seconds of data with a Nikon 50mm lens at f/4, Altair Astro 6nm dual band filter.
