Pacman Nebula


Pacman Nebula

NGC 281 is an 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. A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc. (9200 ly.) from us.[5] Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

This was my first night on this target and I couldn't see it all even after stacking over 2 hours of frames. I struggled to bring out more color without the stars and background blowing up. I think 3-4 more hours will really help.
