Thank Mike. I'll be looking for Astronomik filters eventually, but the baader will have to do in the interum.
I used both Astra Image and ImagesPlus to combine and found Images plus better for combining. Images Plus was more adaptable when working out weight of channel, though AI gives more control over image alignment. The hard part is I like Astra Images RC and ME useability more than IPs version. I'll get a workflow sorted sooner or later
