Just got back from a 3 night trip to the Warrumbungles. First time I'd been up there. Each day a clear morning was followed by afternoon clouds and storms (possibly same all over NSW?
anyone remember the ABC saying a few years ago there would never be any clouds over the country due to global warming). It was never clear until early hours, which meant for a difficult & tiring setting up each night in the dark.
First night, there was an hour delay as a carefully packed camera cable had been left on the kitchen floor in Sydney
The first two nights were not great; guiding star SNR varied a lot, visibly there didn't look the greatest contrast with an intermittent halo around bright stars in the data. I did manage to accidentally capture the NYD aurora on my other camera, which I wasn't aware of until the following day. A comparison between 1st & 2nd Jan can be seen
here.
By the second night I'd decided to stick to one target (Angel Nebula NGC 2170)..I managed another 2 hours but again not the best data.
Final night it was much better- looked like a proper dark sky, I could see the coalsack clearly- and I managed 3 hours of data, reluctantly stopping at 2.30am as I had the long drive back.
I stacked the best 5 hours of data (threw out night one) and the astrobin link is
here.
Cheers
Gary
