NGC 2359 (Thor’s Helmet)
From time to time I obtain data sets from remote observatories. One of my favorite providers is the Insight Observatory with telescopes in e.g. Chile, Namibia, New Mexico etc. One of the data sets I received, was data from the reflection nebula NGC 2359 in the constellation Canis Major.
