Collinder 228 is young magnitude +4.4 large scattered cluster located 6523 light years away in the Carina complex.
Collinder 228, has one of the major concentrations of O-type stars in the nearby Milky Way.
The high-mass unevolved B1V + B1V eclipsing binary system DW Carinae is a member of the open cluster; the beta Lyrae variable (varies between magnitudes 6.16 and 6.49), QZ Carinae (HD 93206) is a member; the Wolf-Rayet star 226 G. Carinae is a member; and  the magnitude +6.45 Wolf-Rayet star HD 93131 is also a member. 

The open cluster was possibly discovered by French astronomer Nicolas Louis de Lacaille using a 1.27 cm (0.5 inch), 8x magnification, refractor at the Cape of Good Hope on the 5th March 1752.
The cluster was rediscovered by Swedish astronomer Per Collinder in 1931 and listed as Collinder 228.
