      NGC 281 "A Closer Look"

      Here is my version of NGC281 using data from Telescope Live. The data was not the best but I was able to process my way through it.


      NGC 281, also known as IC 11, SH2-184, and more commonly known as the “Pacman Nebula,” is an emission nebula located 9,100 light-years away in the constellation of Cassiopeia.

      This nebula measures 20 x 30 arc minutes in size and is associated with the Open Cluster IC 1590.

      This object was first discovered by Edward Emerson Barnard in August 1883, who described it as "a large faint nebula, very diffuse."
