Another over looked target that doesn't draw much attention because of a famous neighbour but this time it's SH2-284 in Monoceros.

I call it The Ring of Fire nebula :)

It also resembles the alien writting from the Arrival movie

Sh2-284 is a HII star forming region of gas and dust located approximately 15 thousand light years from the Earth.

It is observed in the central-eastern part of the constellation, about 5° southeast of the famous Rosette Nebula.
