Today was a day of mixed results. I tested a 5x GSO barlow that I bought last week, it was rubbish , it had a large central reflection that I could not eliminate, so it's going back to the supplier. Next I dropped my Skywatcher Synscan hand controller and it stopped working. So I opened it up and lo and behold it has a Celestron control board inside, I managed to get it working again but only had time for a few images before the atmosphere started to boil. Here are the results.
