Barnard 35 and LBN 878 complex, found in the Orion constellation, is a popular subject among astrophotographers due to its intricate features and rich details. It often appears in wide-field images of Orion, notably recognized for its red and brown nebula that dominates the field. This nebula complex comprises a combination of emission and dark nebulae .
LBN 879, another part of this complex, is closely associated with the variable star FU Orionis and is also known as CED 59. This small bright nebula is encompassed by the dark nebula Barnard 35. The extremely dark portion of the red section of LBN 878 is recognized as the dark nebula LDN 1594.
Further, the Barnard 35 (B 35) molecular cloud with its bright rim (LBN 878) forms part of Sharpless 264. Also known as the Lambda Orionis Ring, it is a giant molecular cloud and H II region, predominantly visible in the Orion constellation. The young star FU Orionis, associated with Barnard 35, is encapsulated by the yellow nebula Cederblad 59 (Ced 59 or LBN 879) .
FU Orionis is distinctive as it is the prototype of a class of variable stars exhibiting extreme changes in magnitude and spectral type. These stars are referred to as FUors and the nebula, Ced 59, was formed from an outburst of the star, a common trait among most FUors .
