NGC 206 – A Huge Open Cluster in the Andromeda Galaxy

NGC 206 is a huge open cluster found in one of the spiral arms of the Andromeda Galaxy. It is composed of about 300 super bright blue supergiant stars. This object presented a lot of difficulty, at least for me, to resolve the individual stars and took several imaging sessions to get the right composition of images.

From the information I found, this cluster spans over 4000 light years and the stars are probably less than 10 million years old.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, 85-minutes combined exposures at ISO 2500 and IISO 3200 using 60 seconds, guided using a Canon 400mm f/5.6 lens with an attached ZWO ASI290MC camera. Image Dates: October and November 2017. Location: The Dark Side Observatory in Weatherly, PA.
