NGC 4755

Hello

Here, out of the oven, my new sketch of the open cluster “jewel box”, the NGC4755, also known as Kappa Crucis.
This open cluster is located in the constellation of the cruise, or crux, a few arcminutes of the star beta Crucis.
The NGC4755 has a magnitude of 4.3 is to 7,600 light years from the sun and has an angular size of 10 arc minutes.
It is visible to the naked eye, easily viewed with a 10×50 binoculars.
It’s a pretty crowded and is a champion of the star party audience that occur below 25 ° south latitude.

Thanks
