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.
