Re:IC 5146
A very interesting mass of diffuse nebulosity surrounding a star of magn. 9.5.
The nebula shows a great deal of structural detail, including several dark
lanes, which are quite irregular. The nebulosity is about 10' in diameter.
Very clearly marked effects of dark occulting matter are shown around the
nebula over an area about 16' in diameter; the number of faint stars de-
creases very abruptly. First noted by Espin, A. N., 3633. A photograph by
Wolf is reproduced in M. N., 64, p. 838, showing that the nebula is at the
end of a long starless rift which extends 2^deg^ west to a large mass of faint
diffuse nebulosity. The Crossley negative is reproduced in Publ. Astr. Soc.
Pac., 29, 94, 1917, Figure 2. 0 s.n.
