Pacman Nebula – NGC281

The Pacman Nebula is another new target for me. It’s an emission nebula in the Cassiopeia constellation. It’s about 9500 light years away and 48 light years across. Between Sep 9 and Oct 8th, I captured 35 hours of data.

I used Siril’s OSC_Extract_HaOIII script and a 60/40 Ha/OIII split on the green channel.
