The plan was to capture H-alpha, OIII ans SII and create a false-colour composite of the narrowband regions of the nebula. Unfortunately, the British weather had other ideas and I only managed the H-alpa part. The nebula is very bright at this band, bearing in mind it was only a 60sec exposure under increasing cloud cover.
