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.
The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy, NGC 253, an intermediate, starburst spiral galaxy in the constellation Sculptor, about 11.4 million LY away, undergoing a period of intense star formation.
This photo was imaged in natural color through my 8" Celestron SCT at 2032mm focal length using my astro-modded and cooled canon 40D DSLR and tracked with a CGEM mount.
I imaged this galaxy when the moon was nearly at first quarter and in the same general direction as the galaxy, so I used the Neodymium filter (AKA Moon and Skyglow filter) instead of the UV/IR Cut filter to try and control the moon glare, I think it worked.
Total exposure time was 5 hours 41 minutes.
