Note (supplied by Bill Gray, Project Pluto): Large vacant region about 4 degrees long NW and SE. This vacant region is about 4 degrees long, extending from RA=15h31m, dec=-32 45' to RA=15h43m, dec=-35 30'. Its average width is about 1/2 degree. It is strongest marked at the north end. There are fragments of other dark markings several degrees west of this.
The SAC 4.0 database comments: "Contains small, bright, reflection nebula". [See also Be 148]
16-inch f/10 SCT (95x, 127x)
This is wonderful to see this long streak completely without starlight. Very elongated in a NW direction and run out of my field of view 95x, which could be around 1degree in size. The diameter could be around 15' or even more. The nebula looks wider around the SE side with the 5.8 HD 140784 situated just outside the nebula's south. The contrast between the nebula and star field is very obvious. New data and sketch in 2007.
