three moving objects in sky above pitlochryI was star gazing trying to pick out different star formations, when my eyes were drawn to a moving object, sphere shaped which was moving very quickly accross the sky, then it was followed by two others, in the same line about 5 secs apart, they then headed North zigzagging and then seemed to disappear. I watched for at least 15 mins but they did not reappear. It was definately not a plane as there were no coloured lights visiable.
