Description

The cloud radar predicted a 3 h imaging opportunity yesterday night. What to do ... starting a new narrowband project? No - I decided for a short session on the Perseus double cluster.

I collected only 120 x 30 sec RGB on this lovely target. So in fact, with 1 h integration time, this is my shortest project ever. However, it turned out ok. 40 subs for each channel is good for denoising, 30 sec is good to prevent stars to burn out.

The double cluster is rich in blue-white super-giant stars and several prominent red supergiants. Both clusters are blue-shifted as they approach us with an average of 40 km/sec (but there are other things to worry about right now).

CS to everyone
