Skywatcher NEQ6 pro mount & Equinox 80mm refractor, Atik 383L+ camera, motorised filter wheel and Astronomik LRGB filters.

Three open clusters in the constellation cassiopeia.

Just over one degree apart so perfect for the field of view of my 80mm scope. Rotated my camera by ninety degrees to frame them better.

Captured the two smaller open clusters, NGC659 and NGC654, on the left and right hand side.

Near the famous double cluster in perseus so overlooked by imagers.

Data collected in a single night.

LRGB image with 3 hours 30 minutes of data. 20 x Lum unbinned, 8 x Red 7 x Green 7 x Blue 2×2 binning, 5 minute exposures.
