This image replaces last years (2005) 5 x 5 minute unfiltered sequence. See here for an image of B 64 (out of field to the West <right>) and LDN 175. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 6333 NGC 6333 = M9 = E587-SC5 17 19 11.7 -18 30 59 V = 7.6; Size 9.3 17.5" (8/1/92): at 220x, bright, fairly large, 4' diameter. The bright core is elongated N-S somewhat like M4. The outliers or field stars appear to extend the halo E-W. The halo is fairly well resolved into two dozen mag 13.5-14.5 stars. The core is very mottled and lively and just breaks up into numerous densely packed mag 14-15 stars. At 420x, the core is easily well-resolved and two very close double stars are at the W and E edges of the halo. The dark nebula B64 is close SW. 8": very mottled, few stars resolved at edges at high power especially on the E side. Dark nebula B64 is close SW. N6356 lies 75' NE and N6342 75' SSE. - by Steve Gottlieb |
