William Herschel discovered NGC 467 = H I-108 = h99 on 8 Oct 1785 (sweep 462) and logged "cB, vL, iR, preceding a very bright star." Heinrich d'Arrest measured an accurate micrometric position.

300/350mm - 13.1" (8/24/84): moderately bright, slightly brighter core.

13.1" (11/13/82): fairly faint, small, round, weak concentration. Collinear with mag 8.1 SAO 109805 3.6' ESE at midpoint and mag 10 SAO 109809 6.9' ESE. NGC 470 is 11' NE and NGC 474 15' NE.

600/800mm - 24" (1/12/13): bright, moderately large, round, 1.2' diameter, sharply concentrated with a relatively large high surface brightness core that increases to a very small, very bright nucleus. Located 3.5' WNW of mag 7.5 HD 7991. First in a trio with NGC 470 and 474 to the northeast. CGCG 385-068 (which has a similar redshift) lies 6.8' SE.
