Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

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. 14 "Faint nebula about 5' in diameter."

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

Ced 55j (IC 426)

Position (1900): RA 5 31.7, Dec - 0 18

Star: 0 1018 (Mp=9.3:, V=9.3:, SpT=B9)

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: 5'x5'

Notes: "Ced 55 j = IC 426. Disc. Pickering 1890 (557). WP 166. (630) Pl 34. R. The nebula is fan-shaped with the star -0 1018 = HD 37140 at the apex. 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."

Modern observations

Steve Coe

Coe, using a 13" f/5.6, notes: " Faint, pretty small, not brighter in the middle at 100X. There is a 9th mag star on the west side, the UHC does not help this nebula."
