Albert Marth discovered NGC 7604 = m 567, along with NGC 7605, on 29 Nov 1864 and noted "eF, vS, bM." There is nothing at his position bright enough to have been seen, but exactly 1.0 minute of RA preceding is CGCG 406-048 = PGC 70974. This galaxy is 3' north of NGC 7583. Assuming Marth made the same 1.0 minute recording error for NGC 7605 = m 568 (observed on same night), then NGC 7605 matches NGC 7583. Karl Reinmuth and RNGC also equated NGC 7604 with CGCG 406-048.

Hermann Kobold independently discovered CGCG 406-048 in 1899 with the 18-inch Merz refractor at the Strasbourg Observatory. He reported it as Kobold 20 (20th discovery) in his big table of NGC positions in the 1907 Strasbourg Annales, Vol 3.

400/500mm - 17.5" (11/18/95): very faint, extremely small, round, 15" diameter, appears to brighten slightly at the center. Can just hold steadily with averted vision. Forms a pair with NGC 7583 = NGC 7605 3.0' S. Outlying member of the Pegasus I cluster.
