Object name: NGC0366
NGC 0366 is a small, type II3p open cluster in the center of Cassiopeia. WEBDA puts it at 5,800 light-years distant with an age of 25.7 million years. The only paper I found on this http://adsabs.harvard.edu/full/1994BASI...22..369P puts it at 7,000 light-years distant and gives an age of 25 million years. WEBDA says it is reddened by 1.256 magnitudes while the paper says the reddening varies across the cluster from 1.1 to 1.4 magnitudes. Indicating dust and gas density between us and the cluster varies quite a bit. The paper concludes it has a higher percentage of low mass stars compared to other clusters of its age.
