Thor’s Helmet, NGC 2359

Post by dcollier »

Thor’s Helmet, NGC 2359 is an emission nebula in Canis Major similar to the Bubble Nebula. However unlike the Bubble Nebula the central star is Wolf-Rayet star WR7. It is approximately 12,000 light years distant. Imaged with a remote telescope from iTelescope, New Mexico Skies Observatory, Mayhill, NM on the evening of 2/4/2021. It has been difficult to get any useable data even from remote scopes on two continents due to the unusual run of bad weather worldwide.
