Woken up at 2:00 AM by drunks on the street, I looked up to see a perfectly clear night sky. With clear nights few and far between I got the RASA 8 telescope out and mounted it in the M Zero. The above image is only 1 hour of total capture time from the middle of a major light polluted city. This ‘scope is very impressive and pairs beautifully with theASI183MC and its small pixels.
