NGC 436 Cassiopeia

No real reason for doing this, just a nice open cluster in Cassiopeia and thought I’d do some photometry on some of the cluster stars using ASTAP, which I did.  I chose a Be star (2MASS J01154089+5849021 / Cl* NGC 436 BOD 54) but nothing revealed on that, or any of the other stars I chose. But then again it would have been lucky!

Ha view of this interesting star forming region at the heart of the Heart Nebula. Various designations for the open cluster including Melotte 15 and IC 1805. The emissions from the Heart Nebula are driven by radiation from the young stars in this cluster.
