Visibility II / V
Only 22r was visually visible (Figure 1). I grabbed a small stack of it, which came off by pinching 22ys (Figure 2). After the stack, I left the camera to shoot at 8 sec intervals. The battery lasted for 2157 pictures - pretty good when the halo ring was just disappearing behind the birch. Images of timelapse from 11.07-15.54 in Figure 3. Timelapse of 10 image stacks, with USM and BR treatments in Figure 4.
