LBN639 & LBN644 in Pisces

This is a very rarely imaged area and most likely an SGL 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 on Astrobin 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: http://www.jthommes.com/Astro/LBN639.htm.  There you can also see that there are several distant galaxies and quasars in this area. 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.

Facts: dual RASA8 with ASI2600MC (no filter), 96 x 3 min so 4.8 hours. Gain 100, offset 30, -15°C (hardly needed as it was -10°C outside). On a Mesu200. Processed in PI and mainly in PS.

I attach the annotated image from Astrobin.

Cheers, Göran

Loving these off the beaten track images. I was looking for a less popular NB target to image tonight, got the rig ready to go but when I looked up from the atlas the sky was 100% clouded over. Maybe next time.

Been there, done it, or rather not done it! I am a sucker for those off beaten ones. Thanks Steve!

That’s a lovely haunting image, I think it shows how cold space is it reminds of waking up to a hard frost, spectacular

I think our galaxy needs a good going over with a mop and bucket, I never realised it was so mucky.  Fabulous image @Goran

Thanks a lot Craig and Martin! Cold and mucky it is😁
