LBN 438

LBN 438 is a galactic dark nebula located in the constellation Lacerta. It is illuminated by interstellar radiation which is known as Extended Red Emission (ERE). LBN 438 is listed a an ionized HII region but has a very weak Ha signal. This image was taken from my suburban backyard. I've imaged this object before from a dark site with a f3.8 10" reflector. See here: LBN 438 10"f3.8. I was curious to see if I could get nearly the same signal as the previous image with a slightly smaller scope at nearly the same focal length and from my backyard. I think the answer is a definite yes. However, it took nearly double the exposure time due to my local light pollution. My 6" refractor provided nearly the same resolution. LBN 438 is part of a much larger molecular cloud including LBN437 which I imaged with a 70mm refractor in 2017.
