thanks. No this is HOO.

I've not used an SHO process on this data because the L Extreme filter doesn't capture Sii. I now have an Askar D2 filter (which captures Oiii and Sii) so I will start gathering data with that and add it to this data to get SHO

Sorry am confused, the image title says SHO, and the colours are SHO Hubble pallette, if it was HOO is would be red and blue….

sorry, you are quite right about the filename. As I say, the L Extreme cuts Sii completely. I used the HOO Normalisation script by Bill Blanshan (here) so I am assuming this produces an HOO image?

Nice Rosette, I've been messing with this one for a while and just cannot get the colours I want yet everyone else seems to manage it
