Well it was 40°C during the day yesterday.. it was hot, damn hot! And I was out on Sydney Harbour for my work xmas party! Ouch!
Last night wasn't much cooler, of course there was no such thing as the scope "cooling down" in that temperature. The skies were clear, I set up and imaged Mars.
Seeing was a little below average. Three images are shown in the attachment below, the left one has had VC deconvolution, the middle has had LR and the right has had ME. I think ME worked best on my poor quality image.
One highlight was while realigning looking through the finderscope using the "two-eyes-open" technique, and zoom there goes a fireball from the Taurus region, heading northwest. Wonder if it was a southern taurid?
Was expecting clear skies this morning for Saturn, but patchy low cloud frustrated my whole morning session. It really was a case of chase the sucker hole. I had to have the gain at 90%+ just to get a 110 white level in k3ccdtools, and that was in a clear patch. I got bits and pieces of avi's (some only 10 seconds long!) which i stitched together in VirtualDub and then gave the usual treatment (including ME deconvolution).
The end result was a very noisy grainy image which took some effort (including a 20% size reduction) to blur back to smooth :) Bad seeing and bad transparency :( What is it with Sydney weather lately.
Anyway, the result is attached.
