Managed to get some NB data on Carina before the fog spoiled things.
HA 3nm 10x4 min, NII 3nm 10x4min, NII to red channel, HA to green and nothing to blue.
This is the equivalent of about 5 nm of a 'HA' filter with the added advantage you can see a bit of variation in distribution of N and H.

I should really get on with properly setting up the mount because the guiding is introducing rotation.
