C19 Cocoon Nebula


Mark Griffith

Swindon, Wiltshire. UK

GSO 8″ Richey-Chretien Optical tube, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik LRGB filters.

Wanted to capture the relection nebula component of this object so didn’t use my hydrogen alpha filter.

Used 5 minute sub frames. Thought I might need longer exposures but the final image worked out nicely.

LRGB image with 3 hours of data.
