NGC 4755 is well placed

Friday 5th Apr 2019

Across much of the world the jewel box open star cluster (NGC 4755, also known as the kappa Crucis cluster) in Crux will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -60°21', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 9°N.

From London, it will not be observable because it will lie so far south that it never rises above the horizon.

At magnitude 4.2, NGC4755 is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.

The position of NGC4755 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC4755 12h53m30s -60°21' Crux 4.2 10'00"

The coordinates above are given in J2000.0.
