The globular is very normal one without any mentioned characteristics. You can see it as a dimmed nebulosity with binoculars, and perhaps it would be fairly difficult to resolve the member stars even if you use medium-sized telescopes with a magnifying power of 100 or so. M30 has a real size of about 75 light years and about 40 thousand light years away. |
