Peter_ButlerNGC 281, also known as The Pacman Nebula, is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. This 20×30 arcmin sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star, B 1. It collectively forms Sh2-184, spanning over a larger area of 40 arcmin. A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies around 9200 light year from us.This is a collaboration with Chuck's Astrophotography, with Chuck capturing the data with his 8" RASA and ASI533MC Pro, and then processed by me using Pixinsight.
