MCG -01-05-036, located 13' N, appeared fairly faint, diffuse, ~0.6' diameter, no significant core. A mag 13.9 star is at the southeast edge of the halo, with the galaxy spreading northwest of the star.

Lewis Swift discovered IC 164 = Sw. IX-5 on 23 Oct 1889 and recorded "pF; S; R; bet. 2 stars, ? cluster of eeF st[ars]." His position is 3.8' ESE of PGC 6666. Howe measured an accurate micrometric position in 1897-98 with the 20" refractor at the Chamberlin Observatory in Denver.

600/800mm - 24" (11/7/18): at 260x; moderately bright, moderately large, round, sharply concentrated a very bright small core and a diffuse halo which fades out without a perceptible edge. The galaxy is nearly collinear with a mag 10 star 3.5' SSW and a mag 12 star 3' NNE.
