Solar Imaging Session - February 24, 2017

The sky this morning is cold and very cloudy. Seeing condition also not that good as well. I was only able to get a shot of AR2638 Sunspot Group through fast passing clouds so I have no calibration frame to even the illumination. But nevertheless, the short 40 sec AVIs still shows an acceptable image despite the weather condition. I decided to stick to my default 0 setting on the tuner.
