Centaurus A with H alpha
SPX350 F4.53, ATK-16HR, Astrodon filters, OAG+Mintron guidecam.
L HaRGB : L=100m Ha=120m RGB=60m each colour all in 5min subs.
This is a glorious galaxy part of M83 group and 12.2 lyrs away with bisecting dust lane from another galaxy merged 500 mil yrs ago. Some blue star burst around dust edge and some H alpha along the dust. A strange H alpha line away from galaxy on the far right with some green in it. Plenty of dusty patches seen against the wide halo.
Thanks for viewing, John.
