Ophiuchus, M10/NGC 6254, M12/NGC 6218
Equipment: Binoculars
S&T Chart: 54, 56, 67
One of my goals was to view Ophiuchus and, if possible, M10 and M12 in its centre. Success!! Both were visible in one FOV of my binoculars. M10 had a fairly bright central core and was obviously a compact globular cluster. It was located almost central in Ophiuchus near 30 Oph, and initially looked like a bright singular star. M12 was a little dimmer and perhaps a little larger than M10. It had a bright core with a diffuse border. |

IC 4665 Time: 10:50 PM Equipment: Binoculars S&T Chart: 54 I was looking around Ophiuchus and there appeared to be several very bright points of light with too many other stars to count, and to perhaps not see given I was using binoculars.But under these skies, it was very evident and bright adjacent to β Oph (Cebarai). It was almost like there was a brighter core with about 10 bright points filled in and around it with stars of varying brightness. |
