In my weekly astronomy post this weekend, I talked about looking for deep sky objects in Scorpius. The weather never did really cooperate, but the clouds added their own strange beauty. Here is a single, 4-second exposure of the head-end of Scorpius – bright red Antares in the “neck”, and sure enough, you can faintly see the M4 globular cluster just to its right.
The cluster is a little easier to see in this digitally stacked rendition of the same area – complete with an intruding airplane and contrails. The tree is blurred, because the stars were moving, and this image tracks them! Unfortunately this was the closest to the horizon I could get with this technique – but I did get a good look at Saturn and Jupiter the same night!
