Deep Sky

Best deep sky imaging is from the 1st to the 2nd and from the 18th on.

You're spoilt for choice now we're into winter, fancy a change from the Messier objects? How about NGC281 (Pacman nebula) in Cassiopeia, NGC 7380 (Wizard nebula) in Cepheus or NGC 7023 (Iris nebula) also Cepheus.

Easier targets are the ever popular M45 and M42.
