Narrowband M33

This is an image of M33 I took using a Lightbuckets 110mm APO ED refractor located in France. The image was taken using narrowband filters for Hydrogen Alpha (Ha), SII (ionized sulfur), and OIII (doubly-ionized oxygen). Ha is mapped to the green channel, SII to red, and OIII to blue. The green patches in the galaxy are rich hydrogen regions of active star formation.
