A bright nebula almost lost in the glow of the very bright M45 cluster, a region about 10-15' south of Merope glows, brighter near the star fading gradually to the south, no detail and ill defined margins

An extensive nebula on the south edge of M45, the Pleiades, best seen when using low powers and placing much of the cluster out of the field, the most visible section fans south from Merope, some nebula visible into the cluster

Nebula in Pleiades, discovered by Tempel, 1859; a faint, extended, somewhat triangular haze, involving at its n extremity, Merope, the bright star sp Alcyone, the lucida of its group. Suspected var., but evidence conflicting. Has been seen with less than 2-in., but invisible in the 11-in. achr, at Copenhagen, possibly from want of contrast in diminished fields; D'A. says there are nebulæ invisible or barely seen in great telescopes, which can be perceived easily in their finders. Wolf is certain that is has not changed since '64. Found readily with 5-½in., '63, Oct. 6. Very feeble, '65, Sept 25; a mere glow when star out of field, 9-in. spec., '72, March 4; '76, Jan. 15, in presence of star, 9-1/3in. spec., 1881, Jan. 31. Goldschmidt saw it as a projection from a diffused nebulosity encompassing Pleiades; so Wolf. Temple thinks this an illusion, but it has been confirmed by photography. The photo. of the brothers Henry shows a remarkable wisp attached to Maia, and a curious narrow ray running through 6 stars for 2½' f.
