First night clear skies, good seeing and transparency. Had a few issues with autoguider lossing lock during the night.

Second night again clear all night. Seeing not as good as last. Autoguider again playing up as we went over the meridian, perhaps a balance issue, time will tell.

Time has told, it's a Binary :-(
