A bright emission nebula located at a distance of 9,800 light years. The evening of 3rd Jan 2026 was dominated by a full Moon for the whole night as it tracked high across the sky. This made any broadband imaging impossible especially as the Moon’s path ran across the majority of this season’s most interesting deep sky objects. That aside, the sky was nicely stable with good transparency allowing excellent guiding with only one dropped frame in nearly thirteen hours.
