NGC 281 Pacman Nebula In Ha Light (Explored)
Part of an HII (ionized Hydrogen) region in Cassiopeia the Pacman Nebula is a bright emission nebula.
Named for its resemblance to the video game character the nebula lies at a distance of around 9500 light years from earth.
This image captured in narrowband Ha light was acquired over 2 nights - 17 & 18th September in strong moonlight. After a prolonged period (seemingly never-ending!) of poor skies was glad to be out imaging again!
Hopefully will have some OIII and SII to add later.
My first narrowband effort with my new Skywatcher Esprit 120ED scope.
40x300s Guided Ha subs. using ZWO 1600MM cooled to -15 and Gain 200.
