NGC 2359, also called Thor’s Helmet, is an emission nebula that is 15,000 light years away. It is a bubble of ionized gas around a hot central star, Wolf-Rayet WR7. It is 16 x 8 arc min in size, and I was pleasantly surprised that I could capture it with my small telescope. These pictures were made by stacking 64 3 minute images (and cropping).
I’ve been learning PixInsight, and I had some fun with playing with CurvesTransformation on this one. So, in addition to a standard view of the nebula, I created one I call “Thor in a Snowstorm”.
