The Iris Nebula (NGC7023)
NGC 7023 is a reflection nebula located in the constellation of Cepheus. The nebula contains at its centre an extremely young star which is believed to have burst into life just 5,500 years ago. Since still incredibly young there is plenty of local dust surrounding the star and when starlight hits the dust it's reflected to become the visible nebula.
The image was taken with a GSO RC8 (Ritchey-Chretien) reflector with an ASI1600mm-cool camera using LRGB filters. The image consists of around 150 luminance sub images and 50 each of RGB all of 2 minutes duration.
Image processing was performed in Astro-Art and Pixinsight.
