A couple of rare clear nights this week with pretty stable conditions so thought I'd battle the mozzies to grab a few shots.
Started on the waxing gibbius moon with a tour around the Mare Humorum. Gassendi & Letronne Craters were nicely illuminated as well as some interesting wrinkles and rilles that I hadn't taken much notice of before. Doppelmayer & Vitello Craters across the basin were more stable than my previous efforts last month and well worth some time with the eyepieces and a capture. A couple of other captures as the seeing fluctuated didn't quite meet expectations...
The conditions were deteriorating quite rapidly after midnight but I couldn't pass the opportunity to catch Jupiter as it approached the meridian with Callisto passing to the North. I opted to stick with the IR685 filter due to the conditions. Grabbed a few captures and selected the best one to post here...and realised this season has not given me a single night of excellent conditions to capture Jupiter
(so far).
The setup...
c14 (non edge) @f11 with asi178mm (IR685 filter)
Lunar: best 2% of 30-40,000 frames, 5ms.
Jupiter: best 5% of 9000 frames (90sec capture), 10ms.
Variable gain to suit the histogram
AS!4, Registax6, PI for some histogram adjustments
Thanks for looking. Comments appreciated!!
