William Herschel discovered NGC 108 = H III-148 = h21 on 11 Sep 1874 (sweep 266) and noted "vF, pL, lbM." JH made two observations, logging it on 16 Sep 1828 as "pB; R; psbM; 20"."

R.J. Mitchell, observing on the 72" on 3 Nov 1855, recorded "E sp nf, the arms being vF, and p one rather the brighter, they are perhaps cut off from central Nucl. by dark spaces, but all this is very uncertain. Night not good."

400/500mm - 17.5" (10/17/87): moderately bright, fairly small, small very bright core, faint extensions SSW-NNE.
