This was the first night of observing from our new (temporary) rental house in south-east Canberra, actually just over the border into NSW in a housing estate called Jerrabomberra.
Seeing was not great, all over the place with some periods of nice seeing (maybe 7/10) and some poor seeing of 3/10.
I've processed one of the images at random, but it came out ok so I'm posting it. I'll post some more images later.
Details:
Scope: http://www.acquerra.com.au/astro/lexx.html
capture: 1 minute each of R,G,B @ 38fps
I've reworked my capture software, now I don't lose any frames cause the hard disk can't keep up - I capture into a ramdisk now and have a separate program that streams that to hard disk. It's made a *big* difference at these high framerates - 38fps @ 640x480x16 = 23Mb/sec sustained write, too much for my poor laptop drive. But if I write into a ramdisk then it's all good.
cheers, Bird
