Description

I originally intended to make this a 1.5h integration. The total imaging time for this capture actually sums 2h. ????? What happened? Clouds =D! I lost many frames in it because of them, and the ramaining 11 best were stacked, and the result is presented here. Not the cleanest and not as good as I intended to be, but, given the conditions, the result turned out to be quite suprising to me. What do you think?

Further adjustments in LR - Saturation and Contrast
