From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 6402 NGC 6402 = M14 17 37 36.1 -03 14 45 V = 7.6; Size 11.7 17.5" (7/1/00): this bright, large, fairly symmetric globular appears elongated ~E-W and ~7'x5' in size at 220x. The bright core is relatively large at 4', very lively and granular with a layer of very faint stars. At 280x, ~30 stars are resolved in the small halo and at the edge of the intense core. A rich, even sprinkling of faint stars cover the core. Difficult to count resolved stars as numerous dim stars pop out with averted vision over the bright background haze, but perhaps 60-70 stars in total are resolved. 17.5": bright, large, 25-30 very faint stars are resolved mostly at the edges which have a ragged appearance. 13": fairly large, broad concentration. About a dozen very faint stars are resolved across the disk. The outer halo fades out smoothly. - by Steve Gottlieb |
