Wednesday 16.10.19

I opened the observatory at 7.00pm and was joined by John at 9.30pm.The sky was clear but with a bright moon.There were security lights inaccessible in a fenced region protecting one of the out buildings.As an exercise I imaged Saturn and the Moon to familiarise myself with the appropriate extensions while John continued his work on double stars.I left at 11.30pm.John a few hours later.
