Photo description / processing
On March 8, I went out of town to photograph the comet. The sky was great, but light pollution near the horizon was really interfering. I also had trouble with flats—it seems that precise focus during shooting is critical, and it's hard to match it later. I wonder how other owners of this lens manage with flats? I'm posting what I got.
