This is the last photo I took during my all-night vigil in the desert. The photo looks generally southwest, up towards the crest of the Sandstone Ridge near the Wave in the Vermillion Cliffs Wilderness of Utah.
My last battery gave out after the thirty minute exposure had finished, but before the camera had finished processing it. My speculation is that the odd purple fringing at the corners was caused by this interuption.
[This photo: 18mm in 35mm terms, about thirty minutes at f/4 and ISO 100, tripod mounted.]

Hi Harold,
You might be right about the fringing here, and I'm amazed that you were able to recover the file even though your battery died! One other thing is that sometimes, when bits of the camera get hot (I seem to remember that this was especially true on the Canon 20D), the sensor actually records that heat, and it shows up as red/purple fringing in the camera. Not sure if you've seen that before with your star trail shots.
