Spectrum of nebula: (not classified)
Classification: Neb associated with mainly one star (which may be multiple) - Fan-shaped object (eg. IC 59)
Notes: "Ced 55 s = NGC 2064 = GC 5355. Disc. d'Arrest. WP 166. (30, 114, 216, 238, 409 Pl 14, 578, 630 Pl 34, 631). R. -0 1077 has two nebulous wisps extending chiefly north-south. NGC 2064 is a part of the southern appendix. 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, pretty small, round, not brighter in the middle at 220X."
Steve Coe (Glendale, Arizona, USA) observing with a 17.5-inch f/4.5, writes in The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "These two nebulae [NGC 2064-2067] are near M78 [NGC 2068] and I could not distinguish what I saw. There is a very dim, elongated nebula at the location with two stars involved at x100."
