Barnard 35 (LBN 878 & 879)

Barnard 35 (B35) is a molecular cloud that is within the Lambda Orionis Ring (a.k.a Sh2-264) a huge molecular cloud and also a hydrogen alpha region located northwest of Betelgeuse in the Orion constellation. One of my favorite parts is LBN 878, the bright rim portion on the top where violent cosmic winds are blowing hydrogen (Ha) gas around. Herbig–Haro (HH) 175 is found in the bottom center of the rim (HH objects are associated with newborn stars). The bright yellow-brown reflection nebula known as GN 05.42.6 surrounds the young star FU Orionis. This lower brown region is known as LBN 879 or Ced 59. Distance to Barnard 35 assuming it is part of the Orion Molecular Cloud Complex is 1000 to 1400 light-years. The bottom right also has an interesting reflection portion rimmed in dense hydrogen gas (Ha).

I started imaged this in January imaging whenever it was clear and finished early March. I was originally more interested in an LRGB image with a bit of Ha but it only seemed to clear when the moon was out so I captured a lot of Ha and am glad I did. The most difficult part of processing was deciding what to bring out. From what I have seen, wide field images of this region accent the Ha whereas localized images focus on the reflection nebula. Although I was able to bring out a good deal of the reflection, my skies are not good enough facing the south to do reflection nebula justice - besides the Ha came out much better than I was expecting. I blended with the Ha and the LRGB until I wound up getting something I was happy with.
