Steve's Notes

===== NGC 1866 30" (11/6/10 - Coonabarabran, 264x): beautiful, highly resolved "blue globular" in the LMC. Appeared very bright, very large, with an intense 1' core surrounded by a 5' halo containing a few dozen very faint stars. The core itself was partially resolved into a number of densely packed stars over bright, mottled haze. NGC 1859 lies 18' NW. 13.1" (2/17/04 - Costa Rica): at 166x, this LMC globular appeared moderately bright and fairly large large, round, 2.5' diameter. The appearance was symmetrical with a faint 2.5' halo increasing to a 1' bright core which was concentrated to the center. There was no obvious resolution although the surface was mottled. Forms an equilateral triangle with a mag 11-12 star 3' WNW and a mag 12-13 star 3' NNW. This is a young populous "blue globular" with an age of roughly 100 million years.
