Steve Coe, observing with a 13" f/5.6, notes: "Pretty faint, pretty small, round and much brighter in the middle at 100X. I believe this is the most southern object I have seen from the U.S. It comes only 8.4 degrees above the horizon for me in southern Arizona."
16-inch f/10 SCT (EP: 2-inch 40mm SW 102x 26' fov, 2-inch 32mm SW 127x 32' fov, 2-inch 14mm UW 290x 17' fov, 2-inch 8.8mm UW 462x 11' fov)
NGC 7144 appears round, fairly bright with an outstanding bright centre. Between NGC 7144 and NGC 7145 is the double star BrO 15 (a rich yellow, bordering onto orange primary with a dark yellow to amber companion).
