Description

Over many weeks I have gathered the data for this, and whilst I am not quite sure what colour a SHO should be for this object, I compared it to others I saw and finally I am pleased with the result. It took quite a bit of fiddling. I have other images to process too, which is remarkable considering the weather - dragging the mount out, putting it away again etc etc, all in one night, time and time again. Nightmare conditions, but better than my 'brethren' up north! Anyway, this was 55 SIIs, 71 Has and 58 OIIIs, all at 3 minutes imaging time each. This equates to 9 hours and 12 minutes. Hoping you are all ok...
