Thor's Helmet - NGC2359 30 Nov 2019 - 4 Jan 2020


Thor's Helmet Nebula, NGC 2359, located in the constellation Canis Major.

This image total exposure time (of used subs) was 35 hours through HAlpha and OIII narrowband filters and was imaged through a 8" SCT at 2032mm focal length using a astro-modded and cooled DSLR.

This image was a bit of a challenge with the Australian bushfires sending a lot of smoke into the atmosphere, causing me to throw out a lot of failed subs. 35 hours are the selected best subs I used on this image but have spent a lot more time in tracking this nebula from 30 November 2019 until 4 January 2020.
