Merry Christmas! Hope you've overindulged, just because
I've always wanted to get my own image of this nebula, it's a stunning target with its rich blue-ish colour and large size. Incredible to think that a single Wolf-Rayet star can produce such a thing. The again, WR stars are in a class of their own.
I found this difficult to process as the nebula's structure, mix of Ha and OIII and colour are subtle and it's taken perseverance and some PI magic to draw them out. There are still numerous aspects that I'm not happy with but as a first attempt and with 'only' 6hrs 20mins of data, it's been another good PI learning experience. Thanks for looking. Alex.
