Hi All
I finally managed to get the SII data last night to go with the Ha and OIII that I took last week. This was taken over 3 nights on 7th, 9th and 15th July using my Takahashi BRC-250 with a Starlight Xpress H9 on a Paramount ME autoguided with dithering using a Starlight Xpress M8C to guide. It is made up of 24x10 minutes Ha, 27x10 minutes OIII and 28x10 minutes SII. No calibration has been used at all so no darks, flats or bias frames. I have used the HST palette so SII=Red, Ha=Green and OIII=Blue. The previous stages of this image can be seen on my website

I'm glad I got the data last night because it is absolutely hammering it down today
Thanks for looking
Best wishes
