Those look very nice Martin, and from Bortle 8 no less. I have the L-Extreme filter so thinking about it I’m covered for narrowband. The Ha would be picked up by the red pixel and the Oiii by the Blue/green? Then I just need to spilt the channel and throw away what I don’t need. If I wanted to go narrower though, say 3nm, I’d need the individual filter (Ha, Oiii & Sii). I realise I’ll sacrifice resolution and have to image for longer but it’s better than dropping another $3500 on a camera.
