Published comments

Pickering, E.C. (1890)

Detection of new nebulae by photography. Annals Harv Coll Obs., 18, 113. Bibcode: [1890AnHar..18..113P]

Photographs taken with the Bache telescope, a photographic 8-inch f/5.5 doublet, covering 10 degrees square, were examined by Mrs M Fleming with a magnifying glass.

Table 1: List of nebulae (p115)

No. 17 "Nebulous band 3' wide extending 10' north preceding from DM -7 1142. Probably connected with No. 12 through No.15 [of Table 1]."

Cederblad, S. (1946) [VII/231]

Ced 55k (IC 430)

Position (1900): RA 5 33.7, Dec - 7 8

Star: 7 1142 (Mp=4.96:, V=4.88, SpT=A3)

Spectrum of nebula: continuous spectrum (inferred from sp.t. of illuminating star)

Classification: Neb associated with mainly one star (which may be multiple) - Fan-shaped object (eg. IC 59)

Size: 11'x11'

Notes: "Ced 55 k = IC 430. Disc. Pickering 1890 (557). WP 67. (630) Pl 34. R. A fan-shaped appendix to d Orionis = -7 1142 = HD 37507 = Boss 7039. Ced 55: The Orion region. History and bibliography: (118, 119, 186, 188, 191, 276, 352). The nebulous groundwork and the exterior nebulosities: (20, 21, 26, 53, 58, 78, 142, 143, 186, 191, 206, 207, 278, 279, 281, 282, 289, 305, 312, 438, 480, 519, 540. 541, 593, 594, 595, 620, 625, 628, 630 Pl 34, 663, 675, 715, 726 No 41, 769, 782, 802, 818). R. It is shown on several photographs, e.g. (630) Pl 34, that the whole region of the constellation Orion is filled up by vast masses of nebulosity. As is well known, there are several condensation which seem to stand out from the general background, and which have been separately discovered and studied. Such subnebulae, will be individually discussed below. Taken as a whole, No 55 of the catalogue should be classified as C. 2 in addition to the separate classes of the subnebulae."

Coe, using a 13" f/5.6, notes: " Faint, large, elongated 3 X 1 in PA 135 at 100X. This streamer of nebulosity has a fuzzy 10th mag star involved."
