Contribution Index (beta) is system to reward informative, constructive, and valuable commentary on AstroBin. I had to do a second sessions for this, because of a Focuser issue on my SV503, which was maybe caused by some clouds. The global conditions were very wet and the seeing was bad. The waxing moon was also not very helpful ...
