I just processed this data from September 2nd 2010 to keep my hand in 🙂 This colourful cluster (which is rarely imaged) is Stock2 and it lies in the constellation Perseus – right next door to the Double Cluster – which is why it rarely gets a look-in. This pretty cluster covers a lot of ground as this image was taken with the Sky 90/M25C combo which gives a massive 3.3 x 2.2 degree field of view. In this image North is to the right as the camera was used in “portrait mode” on the Sky 90.
