Exposure Details HaOIIIOIII using 3nm Astrodon filters and AO-X.  The hydrogen Alpha was 210 minutes and the OIII 165 minutes.  The Ha was added at 50% opacity to form a luminance layer.

The Hubble palette version used an additional 400 minutes of Ha (5nm filter). 15 minutes of RGB were taken for the stars.

Description This vast and complex emission nebula surrounding the star Eta Carinae is easily visible to the naked eye and a fine telescopic object.  Eta Carinae itself is surrounded by a 15" wide nebula called the Homunculus, some indications of which can be seen in these images.
