LBN644 - Dusty Region in Pisces

The dusty nebula, LBN644, is near another dusty nebula I did last year, in fact, Göran Nilsson did an excellent job capturing both nebulae in the same FOV with his wider field dual RASA set up. This object is located in the constellation Pisces and is part of a larger structure known as the MBM 3 molecular cloud. Information is sparse for this object however I did find a distance estimate of 807 to 858 light-years from Jim Thommes website (http://www.jthommes.com/Astro/LBN639.htm). Several galaxies which are over 500 million light-years away are visible in this image as well as some quasars. This is sort of a debut as Goran's widefield shot is the only other image of LBN644 currently on Astrobin.

I really love capturing these types of dark nebulae but the Bortle 5.5 skies of southern Connecticut are not ideal for this. One thing you can do to lessen the effect is take a lot of exposure which is what I did here. The stars came out really sharp and colorful which I am happy with. There is a lot of other 'stuff' in this field such as galaxies and what looks like a planetary nebula almost in the center of the image. You have to look closely to see some of these - not that I am advocating you to pixel peep.

Dates: 10-14, 10-15, 10-18, 10-19, 10-20, 10-21
