The central part is vacant, giving the object the general appearance of a pear-shaped ring, rounded at the southern end and pointed at the northern end, which is directed approximately toward & Orionis, 27' distant. There are flamelike protuberances on each side at the north. Quite faint. 1 s.n. A smaller mass of diffuse nebulosity, somewhat resembling I 423; 2.5 x 1'; the The Crab Nebula in Taurus; Vol. VIII, Plate 9. Planetary? 0 s.n. DESCRIPTION-(Continued) A wonderful mass of bright, diffuse nebulosity covering an area nearly 30' x 20'. Described in the N. G. C. as a very large nebula of the Merope type with e Planetary. 0 s.n. This is one of the most wonderful regions of the sky; it is too large to be recorded on a single Crossley plate, but the portion involving I 434 and 2023 is reproduced in figure 5. At the north, beyond the edge of the illustration, is Orionis, to the east of which lies the beautiful mass of diffuse nebulosity, 2024. This is shown in Vol. VIII, Plate 13; it covers an area about 20' x 16'; shows a wealth of structural detail, and is divided into two irregular masses by a wide, irregular, dark lane. I 434 is a line of rather faint diffuse nebulosity extending for fully 60' south from Orionis, in p.a. about 175°; it bends somewhat to the east at a point about 10' s. of and the halation effects about the bright star make it difficult to say whether the ray actually reaches . On the west of the ray is very faint nebulosity and numerous faint stars; to the east of it practically none. 2023 is a mass of bright, irregular, diffuse nebulosity about 6' x 4', surrounding a star of magn. 9; it shows a number of sinuous dark lanes, of which one on the eastern side is very clear-cut, and suggests absorbing matter. Further east is I 435, a similar, but smaller and somewhat fainter mass of diffuse nebulosity, 3' in diameter, surrounding a star of magn. 8.5. But the most remarkable feature of the region is a dark bay which juts into and bifurcates I 434 at a point about 30' s. of . This is 5' wide and 4' deep, like an inkblot except for a faint wisp in its northern portion, and as clear-cut and sharp as a knife-scratch on its western and southern edges; a beautiful example of a "dark nebula." 0 s.n. Large, fairly bright; exceedingly irregular, with curious loops; many stars involved. Made with the D. O. Mills Reflector at Santiago, Chile. Vol VIII, Plate 14.

Could see no nebulosity Fairly bright, 4.5 x 1' in p.a. 147°.

Eff. 3 s.n. 2174 and 2175 are simply brighter portions in a very large mass of diffuse nebulosity, nearly square in general outline, 22' long; roughly central about a star of magn. 8. The brightest patch is that about B.D. +20°, 1288, and is comet-shaped. Another patch of fainter matter is about B. D. +20°, 1293. The large nebula shows much delicate structure, with curious, sharply defined rifts and lanes. 0 s.n. Planetary. 5 s.n. Planetary. 1 s.n. Cluster and nebula in Monoceros. An area nearly a degree square is filled with very irregular diffuse nebulosity; some curious rifts in northeast portion. Barnard, A. N., 122, 253, 1889, gives a drawing from visual observations, depicting the main portion as a ring 40' in diameter; the negative shows but little resemblance to the drawing. Swift's nebula, 2237, is a brighter patch in this region. Some of the brightest patches of nebulosity are around the central bright stars of the cluster. O s.n. A star of magn. 9.5 surrounded by an irregular mass of diffuse nebulosity; the brighter parts are 2' x 13; exceedingly faint extensions make the total diameter about 4'. The brighter matter is arranged in two lobes on either side of the star along an axis in p.a. 175°. Shows a slight resemblance to the planetary form. The object lies in a large vacant area about 15' in diameter; the cutting off of the fainter stars is quite marked. 0 s.n.

About 5' x 3' in size; but little structural detail. O s.n. Diffuse nebulosity of Pleiades type filling a space about 3' square about a star of magn. 8.5; it lies in a large vacant area.

C., but a bright, irregular spiral, 57" x 44" in p.a. 167°. There is no true nucleus; a line of bright matter extends along the major axis to the s. It is perhaps a spiral consisting of a single whorl, obliterated at the southern end by occulting matter; this whorl gives it the appearance of an oval ring. It is astonishingly like a planetary in its general form, but observations by Messrs. Campbell and Paddock with the 36-inch refractor have shown that its spectrum is continuous. Very bright; the brightest part is a condensation on the northwest edge, which shows well in a 2m exposure. See Figure 6. 26 s.n. 3 A very narrow spindle 5' long in p.a. 17°. An edgewise spiral; the faint nucleus is displaced to one side, and there is evidence of an absorbing lane. 2359 7 12.9 -13 2 2366 7 18.3 +69 13 23712 7 19.3 23725 II 2189 7 19.5 +29 41 +9 7 2392 2403 7 23.3 +21 7 49 24371 7 37.2 -14 24385 2440 7 37.5 —17 58 |
