NGC 6744 = ESO 104-042 = AM 1905-635 19 09 46.2 -63 51 25 V = 8.3; Size 20.0x12.9; SB = 14.2; PA = 15d 18" (7/10/02 - Magellan Observatory, Australia): this massive barred spiral appeared fairly bright, large, oval 3:2 ~N-S, roughly ~8'x6' with a large, bright core. About a half-dozen stars are superimposed over the face of the galaxy - possibly some of these are small HII regions. A hint of spirality was suggested within the outer region but no definite spiral structure was observed. NGC 6744A lies 12' NW (not noticed). 20" (6/29/02 - Bargo, Australia): bright, large, elongated 3:2 SSW-NNE, ~9'x6'. A bright, oval core or bar is surrounded by a moderately low surface halo with an impression of "motion" or arcs embedded within the outer glow. | |||
