Description

NGC 2020 is an emission nebula and HII region surrounding the Wolf-rayetstar BAT99-59. It is located in the largeMagellanic cloud, in the constellation Dorado.The nebula was discovered on 30 December 1836 by John Herschel. Together with NGC 2014 it makes up what is called the Cosmic Reef.

I imaged this back in February 2021 but didn't get far with processing so gave it another go.Processed in astropixel processor and photoshop. It is composed of 20 x 300 second exposures using the ZWo ASI2600mc and the L-eXtreme filter.
I always cool the sensor to -10, it seems a common choice throughout the forums etc. I still stick with gain of 100, again it seems a popular choice.
