I think this is partly an Astrobin premiere. Finally, after more than two weeks I had a few clear hours, and I was inspired by Kurt Zeppetello's recent image of LBN 639 to aim at this area with my dual-RASA8 rig. These nebulae from Lynd's catalogue of Bright Nebulae are part of the MBM 3 molecular cloud. I have not found any other images of LBN644 on Astrobin and in addition to Kurt's image I have only found one other image of LBN639 on Astrobin, which is by Jim Thommes who also gives some info on his web site, including a relatively close distance estimate of about 800 light-years:

The close distance of the nebulosity means that it is not IFN from the outskirts of our galaxy, but still it is very faint, so Kurt's effort to image these at a light polluted site borders on the heroic. Fortunately I have a Bortle 2-3 sky although this time SQM showed 21.0, so not the best of nights.
