Hi All
I have managed to get the OIII and SII data to go with the Ha data I took just over a couple of weeks ago on this subject. It is made up of 18x10 minutes each for Ha, OIII and SII which were mapped to the HST palette so SII=Red, Ha=Green and OIII=Blue. It was taken with the Starlight Xpress SXVF H36 and Takahashi BRC-250 on a Paramount ME autoguided by a Starlight Xpress Lodestar and TMB 115 (the Ha data was guided with the starlight xpress M8C), now on to the next stage which is Pickerings Triangle. Two earlier attempts can be seen of this subject from last year and also the year before when I first started imaging on the Nebulae page of the image gallery on my website
