Weather here has been awful for DSOs. Not wet, but so much cloud. Stepped out tonight with super pair of Canon 10x30IS binoculars. Just down from Cassiopeia is a very pretty open cluster which is mostly naked eye visible but binoculars add so many more stars.
The cluster is centred around alpha persei and all the members have the same proper motion across the sky – consistent with recent stellar genesis across the group – hence the “moving cluster” name.
The cluster is also known as Melotte 20 and Collinder 39 from various catalogs and is also part of the Moore winter marathon.
