Description

Sh2 184, NGC 281, Pacman Nebula.

A bit of a different wide field perspective using the following narrow band filters (10)Halpha, (14) NII, (15)OIII, (11)SII filters used were 3nm Astrodons with 20 minute exposures. The yellow filter was (8) 5 minute exposures.

In an attempt to bring the faint bckground out I found that any smoothing reduced the SNR and the faint data was lost. So the image is a bit crunchy.. When I refield this astrograph I'll likely take a lot more data to smooth things and further bring out the faint background.
