LBN 437 is a nebula complex located approximately 1200 light-years away in the constellation Lacerta. I call it a complex because it consists of two different types of nebulae, one being a molecular cloud of dust and the second being hydrogen gas. The molecular cloud is actually LBN 437 and the hydrogen gas is part of a much larger emission nebula (approximately 7 degrees) designated as SH2-126.
My FOV was only a couple of hours per night so I imaged every opportunity I had in October which worked out to 14 nights.
I have looked at several versions that other people have taken of this nebula and noticed there is quite a variation in how they look, much more than in other objects. I believe the reason for this is because they are completely different types of nebulae and require different methods for enhancing them which often interfere with each other. Try to bring out the Ha and the masks of the molecular dust and visa versa. Because of this it wound up being one of the most difficult objects I have had to process. I did a bit of star reduction but kept it at a minimum because I really like the star field.
