Had trouble getting the Cartes du Ciel/PicGoto combination to work correctly tonight. I tried to start from nu Oph and each time after synchronizing there and then doing the goto for M16 the chart would jump to some position to the west of where it really was. So a switched to alpha Sct, synched there, and did the goto; no problem that time. Despite looking promising on the forecast, conditions are not great tonight: gusty wind, & poor seeing and some smoke in the air. So guiding performance is terrible, worse in RA than in DEC. But I haven't been to the Eagle in a couple of years, so I thought I'd give it a shot.
