LBN 437 is a molecular cloud in constellation Lacerta in a distance of 1200 light years. The red hydrogen glow is part of the much larger Great Lacerta Nebula (Sh2-126), a huge star forming region, part of Lacerta OB1 association.

I changed the mount in between night 2 and 3, because the EQ6R Pro a bit too massive for this small setup. However the CEM26 is disappointing at this point. Still trying to tune it for better tracking.
