Thanks guys

. Dennis I thought Cleveland point would lessen the Brisbane light pollution to the south east. I think that's the Gold Coast lighting up the horizon in #1 and 2.
As I was imaging a police car pulled up and an officer asked me (who was with binoculars around neck, standing motionless in front of a tripod in the shadows of a streetlight) what I was doing.
At that time the comet was not longer visible easily to the naked eye so I brought the camera over to them and showed them some pics - not spectacular - "Oh, that streak?" was the reply. I said it would have been much better a few days ago. Anyway, they drove on leaving me thinking how strange this hobbsession is sometimes
