NGC 3717 = ESO 439-015 = MCG -05-27-015 = UGCA 238 = PGC 35539 11 31 32.0 -30 18 28 V = 11.2; Size 6.0x1.1; SB = 13.1; PA = 33d 18" (3/19/04): moderately bright, moderately large, very elongated SSW-NNE, 2.5'x0.5', small brighter core, fades at the ends of the thin extensions. A mag 13 star is attached near the NNE end and this galaxy appears like a dagger attached to the brighter star. Located 7' ESE of mag 9 SAO 179951. Photographs reveal a strong dust lane but this was not noticed visually. 8": faint, small, very elongated ~N-S, thin, moderately large. Located 10' SE of mag 8.5 SAO 179951 and 1? SSW of N Crateris (V = 5.8). Forms a pair with IC 2913 7.3' SE (not seen). | |||
