Frank Muller discovered NGC 7758 = LM 2-475 in 1886 and reported "mag 15.5; 0.3' dia; irr R; sbM; double star mag 10, north following 50 seconds." His position is fairly accurate and the double star is HJ 3218.

400/500mm - 17.5" (12/16/95): extremely faint and small, requires averted. Position verified using GSC chart. Appears barely nonstellar, ~10" diameter though possibly only the core observed. Forms a near equilateral triangle with two mag 14 stars 3.1' NNE and 3.6' ENE.
