IC1318a (the most interesting part), July 24, 2015


We are blessed with clear-ish skies on a weekend with a quarter moon, which works for narrowband.  IC1318a is near the star Sadr in Cygnus, a prominent summer constellation.  I've shot this object before, but I've a goal to shoot OIII and SII this time, also, and make a color frame of it.  The star at the center of the frame is HD194789, a type B star about 1,050 light years away.
