Description

Oh the clouds, the clouds. Worst nightmare of any astrophotographer... Well, I managed to get 10 minutes of animation material. Based on these 12 frames (20 sec capture, about 30 sec between captures) this would have made a pretty nice animation if I could have taken about an hour's worth of data. But maybe next time with better luck! 

6.5 ms and gain 125 in Firecapture. 8 bit high speed and a bit over 3000 frames per video. 400 best frames are stacked. Taken with an alt-az mount and cropped as needed.
