Francis Leavenworth discovered NGC 7157 = LM 1-244 in 1886 and recorded "mag 14.0; vS; R; sbMN; B double star precedes 8 sec; env 16.0." His position is 0.7 minute of RA west and 1.5' south of ESO 532-003. A mag 10/14 pair at ~12" separation is 2.8' west, matching Leavenworth's description, so the identification is certain. Herbert Howe, though, observing with the 20" refractor at Denver, reported in 1898-99 "There is no bright double star in the vicinity, and I could find no nebula. Possibly, however, the abbreviation "BD" is here used for "Bonn Durchmusterung." Spitaler also failed to find this." Despite their failure (the double star is probably very difficult), the identification is certain.

400/500mm - 17.5" (8/3/94): very faint, fairly small, round, 0.7' diameter, low even surface brightness. A mag 14.5 star is 1.9' N of center. Located 2.7' ENE of mag 9.3 SAO 190762.
