This is NGC 2359, also known as Thor’s Helmet. This image is from four observations using the Slooh.com Canary One telescope in December 2018.

I created this image by aligning and stacking using MaxIM DL; I applied some filters to remove noise. I also used a Photoshop Curves adjustment to darken the background and bring out the detail in the nebula.
