Historical observations

William Herschel (c.1784)

Synonyms: H IV-038

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a considerable star affected with vF milky chevelure."

Burnham, S.W. (1894)

Publ.Lick.Obs. Volume 2."Observations of Nebulae with the 36-inch Refractor of the Lick Observatory", p 168.

This is a large nebula surroudngin a wide double star. The nebula is IV.38 (= h381). The double star is H 2298. It is much too wide to be of any interest as a double star. The description of h 381 is: "The large star of a double star has a very strong nebulous burr." The double was estimated (Fifth Catalogue) 90deg; 35''; 8-9, 10th mag.

The large telescope shows that the principal star is centrally placed in a faint nebula, which is considerably extended in all directions. It is very much like the planetary nebulae so far as the central star is concerned, but lacks the definite boundary which charaerizes all nebulae of that class. The large telescope also shows, what is of more interest than anuything heretofore seen in connection wiht this object, that this central star is a very close pair. It is much too difficult to have been discovered with the large reflectors with which the nebula has been observed. I have not looked at it with the 12-inch here; under favourable conditions the elongation would probably be detected, but it could not be properly measured with such an aperture. ... There are a number of other nebulae in this vicinity which were also examined..." [NGC 2167, 2170, 2186 & 2185]
