    This image was made from unguided 1-sec subexposures with 2×2 binning (all of which are Observatory requirements), which were integrated to produce master images at Ha (for 1.27 hrs), LUM (1.17 hrs), Red (0.97 hrs), Green (0.47 hrs) and Blue (0.80 hrs). Al broadband data were collected when the moon was below the horizon, and Ha data were obtained when the moon was less than ~ 16% illuminated.
