NGC7789
NGC7789, originally uploaded by ThinkingCamera.
This is one of my favourite star clusters and this is the best image I have ever made of it. It is a collection of old stars (hence the colour) in the direction of Cassiopeia. The stars have used up much of their hydrogen and bloomed into “red giants”.
15 x 20second frames. CPC800 Hyperstar Telescope. Atik 320e camera. Quite a bright moon and there was thin cirrus cloud.
Keep up the good work with you photos. It is really great knowing that you have this great ability to find and photograph. Most os us struggle just to try and set up a telescope. Thanks for your posts, I really enjoy them.
