The Double Cluster

One of the best known objects in the sky, and one of the most spectacular through a small telescope, is the Double Cluster in Perseus, situated close to the border with Cassiopeia. In this LRGB image, the two clusters NGC884 on the left, and NGC869, were captured through the Equinox ED80 using the Atik 31L+ with Baader LRGB filters. 20 x 30s exposures were taken through each filter. The diffraction spikes – I’m still not sure if I like them or not! – were added in Photoshop using Noel Carboni’s actions.
