Whilst riding out storm Ciara I used up the last of my current itelescope points by getting two hours on Thor's helmet

Didn't know of this target till I joined astrobin, its one of my faves

Did an hour Ha which is in red, hour 0iii which is in blue , created synthetic green channel

Shot from Spain using telescope 16 which is a 150mm aperture , 1100mm focal length F7.8

I did do some basic pre work but could have done with more focal length , this is a heavy crop

The full (995) moon was up so big discount on cost , justify this in my own mind cause this target only ever very low in my skies and the wrong side of the house

Wiki tells us ....

NGC 2359 (also known as Thor's Helmet) is an emission nebula[3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.

It is also catalogued as Sharpless 2-298 and Gum 4.[4]

The nebula has an overall bubble shape, but with complex filamentary structures. The nebula contains several hundred solar masses of ionised material, plus several thousand more of unionised gas. It is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star.[5] The expansion rate of different portions of the nebula varies from 10 km/s to at least 30 km/s, leading to age estimates of 78,500 - 236,000 years. The nebula has been studied at radio and x-ray wavelengths, but it is still unclear whether it was produced at the class O main sequence stage of development, as a red supergiant, luminous blue variable, or mainly as a Wolf-Rayet star.[2]

NGC 2361 is a bright knot of nebulosity on one edge of the central ring of NGC 2359.
