The exposures that made up this image were all taken in astronomical twilight with no moon. By the time it actually got dark here at that time of the year, M27 had already passed the meridian and was no longer in a usable imaging position from my back yard location (wires overhead, heat off the house and bad LP from the city). So all I got was an hour or less of pre-darkness over a couple of nights.
Still, the image turned out pretty well all things considered.
