The Double Cluster is the common name for the open clusters NGC 869
and NGC 884, which are close together in the constellation Perseus.
Comet C/2017 T2 (PANSTARRS), M36 star cluster and the
Fly Nebula, all in the constellation Auriga. The comet is in the upper left.
Just in time for Halloween, the Ghosts of Cassiopeia. The remnants
of a large nebula, the remaining clouds of gas and dust are illuminated by
the star Gamma Cass in the constellation Cassiopeia.
There are lots of things to see in this image but at this resolution it all looks pretty small.
On the left is the open star cluster NGC 752 which includes a carbon star, the brightest star in the cluster.
To the right of the three bright stars in the center, there are many small galaxies visible.
Tighter crop of NGC 752, the carbon star is the brightest yellow star in the lower center.
And a tighter crop of the galaxy cluster.
NGC 185 and NGC 147 are dwarf spheroidal galaxies located 2 to 2.5
million light-years from Earth, appearing in the constellation Cassiopeia.
