Heart Nebula (IC1805), Hubble Palette
Position:
RA: 02h 35m 04s (J2000)

Description:
IC 1805 is a young star
cluster surrounded by Ha emitting nebulosity, located in the
constellation
Cassiopeia. There
is a
great
deal of interesting detail within IC 1805 that can
be best appreciated in Ha light, as shown here in
an image that I captured several years ago.
More information about this region can

Gendler's website.
