Massive Asteroid BL86 Approaches Earth

Mountain-sized asteroid BL86 (also known as 357439) came hurtling towards its near-miss with earth today, and I caught it on my camera. Here's the time-lapse video, both an edge to edge 16:9 crop at 200mm, then a second copy cropped to 1080p. Look in the center as it moves from lower right center to upper left center:

Both were assembled from 119 separate images of the sky, taken with a full frame DSLR and 70-200 mm lens, on a star-tracking mount. The evening sky is becoming bright with the moonlight, so I lowered the they ISO sensitivity to 2000. I tried a second camera using an 85mm lens at f/2.2 without a tracking mount, but I probably won't get to that footage this week so see whether the asteroid shows up well..
