Most of the images I shoot these days are the result of long-term planning. Not this one. An unexpected string of clear nights had me scrambling to find a target. My criterion was simply "what offered the greatest data acquisition time." Soul Nebula (IC 1748, SH2-199) was the best candidate, even though it was not on my "long-term target list." Lucky for me that serendipity took over because I really like the image. I think there may be a lesson here. While careful planning is a big part of astrophotography, sometimes the best images are those offered up by the night sky.
