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

Emission, reflection and dark nebula in cygnus. The reflection component gives the nebula it’s pink colour and blue colour round the edges.

Wide field image to capture the dark nebula, barnard 168, associated with this object

Dark nebula is a gas and dust cloud stopping the light of the stars behind it reaching us.

Spent a good ten minutes on the framing to make sure I captured as much of the dark nebula as possible.

Data collected on three nights. 23rd, 25th & 26th July.
