John Herschel discovered NGC 6072 = h3620 on 7 Jun 1837 and recorded "pF; R; vgvlbM; 60"; with left eye slightly mottled; but not resolved."

200/250mm - 8" (6/19/82): faint, fairly small, round.

300/350mm - 13.1" (4/10/86): moderately bright and large, roundish, 1.0' diameter, fairly prominent with a UHC filter at 166x. No structure at 332x although this planetary is far south for viewing from northern California.

400/500mm - 17.5" (6/30/00): at 280x using a UHC filter this southerly PN appeared fairly bright, round, 60" diameter. The surface brightness was uneven with an irregularly brighter rim and a slightly darker center.
