Last night saw some more excellent seeing around here for a short while at about 9pm. I'd estimate that it was very close to 10/10 for about 15 minutes or so while I was capturing.
Here's one of the images, right in the middle of the best seeing.
Thanks Dennis, it's taken all day to process the data... Ken, that dark spot is a storm of some sort, it's been hanging around the same location (relative to the grs) for a coupla months now. Dunno what's going on there but it's showing up in everyone's images of that area.
Thanks guys, I'm surprised too that there are still periods of good seeing in the middle of Canberra winter... This is our first winter at Murrumbateman so I really don't have any history to look at, but there seems to be a trend of stable temperature and good seeing around 9pm every night that lasts about 30 minutes to an hour. After that the seeing goes down the drain in a big way.
So I'm trying to be ready to image at 8.30 each night, and just hang around waiting for the good stuff :-) last night (Monday night) was a writeoff, there was a high haze that never lifted.
Next year is gonna be fun... permanent observatory, two scopes, synchronised capture... mmmm.
I've made a short set of 3 video clips, for each of red,green and blue from the raw data for this image for those of you who have more bandwidth than you can use :-)
Click on the link to the 20070722 image and you'll see 3 avi files, each one is about 4Mb in size.
ps, I used Xvid as the codec, if media player doesn't understand it you may have to install the free divx player and codecs from www.divx.com
The video quality is not great, but I tried to find a good tradeoff between small size and showing enough detail that you could get a feel for the seeing.
