This image is a combination of 138 exposures of 3 minutes each in 2x2 binning, with a 40cm F/4.5 Newtonian (with Televue Paracorr) and QSI583wsg CCD,
on December 7, 2012 and January 12, 2013 from Beilen, the Netherlands. The little white line above the nebula is the track of asteroid 29763 (1999 CH20)
(magnitude 17.7) This is my longest exposure so far. Processing in PixInsight 1.7, final touches in Photoshop CS5.
