William Herschel discovered NGC 1407 = H I-107 = h2570 on 6 Oct 1785 (sweep 459) and recorded "B, R, mbM or large nucleus, about 1.5' diameter." JH logged it as "vB, L, R, first vg then vs, vmbM; 3'."

200/250mm - 8" (10/13/81): bright, small, round, small bright core.

300/350mm - 13.1" (1/18/85): bright, fairly small, bright core, stellar nucleus. Forms a wide pair with NGC 1400 11.6' SW.

400/500mm - 17.5" (12/11/99): bright, moderately large, round, 1.5' diameter, bright core, nearly stellar nucleus. Brightest in the NGC 1407 Group (LGG 100), which includes 8 NGC galaxies and IC 343.

600/800mm - 24" (1/1/19): at 260x; very bright, very large, round, 2.5'-3' diameter. The galaxy displayed three distinct brightness zones that were sharply delineated. The large halo was fairly smooth, but the sharply concentrated with a very bright core. The core has a sharp brightness spike with an extremely bright nucleus!

A number of galaxies are nearby including NGC 1400 11.5' SW, NGC 1402 10' WNW, IC 343 8' N, IC 345 21' NE, IC 346 29' NE and several more.
