Description

I am sure you recall my Rosette HOO nebula from the other day, well here it is again but with 94 stacked SII subs in addition. I struggled to process this because in all honesty I was expecting more from the data, with such a significant addition of integration time - but then the detail from the Ha and OIII subs was pretty significant previously. What it has done, however, is provide the regular SII colour change, and thus a standard SHO colour-palette. But, in order to be a bit different I applied some hue, a and b shifts to the image in order to create  a slightly different picture, which is in the revision option - my daughter's preference. So, 52 Has, 54 OIIIs and 94 SIIs, each at 4 minutes long exposure time. Thus the integration time was 13 hours and 20 minutes. Thanks everyone and have a good day!
