That was also my initial and immediate reaction but I think there is a reason for the lengthy exposure ... it will serve as the basis for the luminance layer of an LRGB composite and, as a result, the longer the exposure for "L" the better.
If I am off base with my assumption, Sean, please advise. :-)
