Observe glorious CASSIOPEIA'S rich deep-sky bounty

摘要

Cassiopeia's main currency is its superb collection of alluring open clusters, three of which, Messier 52 and a couple of glaring omissions from Messier's catalogue, I'll cover here. There's also a sprinkling of decent nebulae, especially ripe for imaging, some fine double stars, including the outstanding multiple star iota Cas, and, lying further afield, some challenging Local Group galaxies.
