NGC281 is also known as the Pacman Nebula. This was my second attempt with this target, but my first with narrowband filters.
I tried to do a blend and get an RGB look with this. I, however, do not remember the exact pixel math formulas I used to get this result.
I’ll try again in the future to add more data to this and see if I can come up with more details on this image. Maybe even add some RGB data for star color.
