William Herschel discovered NGC 4152 = H II-83 = h1112 on 21 Mar 1784 (sweep 182) and noted "F, pL, r." JH and d'Arrest both observed and measured this galaxy four times.
400/500mm - 17.5" (4/25/98): moderately bright, round, ~1' diameter, moderately concentrated with a brighter core ~20" in diameter. Halo increases to nearly 1.5' diameter with averted vision. Transparency poor due to smoke.
