94mm f/18 Tully Achromat

Planetary: somewhat elliptic: very bright for an object of this nature; pale blue; not well defined in the 5-1/2ft. achromat, but bearing magnifying more like a planet than a common nebula. One of the finest specimens of these extraordinary bodies, to which their discoverer, Herschel, assigned a distinct class. E. of Rosse finds a very thin ray on either side, which I saw with Huggins's 15-in. achr. La. detects within it an elliptic ring. Buffham, 9-in spec., an opening. Se., who made its diameters 25" and 17", saw it sparkle, and thought it a heap of stars. The spectroscope of Huggins reveals the astounding fact that it is a mass of incandescent gas. About 1-1/3° p [nu Aqr], 5 mg.
