About NGC 6124
NGC 6124 (C75) is catalogued as an open cluster in Scorpius. Its J2000 position is RA 16:25:19, Dec -40:39:12, corresponding to 246.3321 degrees RA and -40.6611 degrees Dec. The local catalogue places it about 1,500 light-years away. Its referenced angular extent is approximately 48.1 by 48.1 arcminutes.
Observing tips
StarWatchr rates this as a very easy target at magnitude 5.8. It is associated with summer observing, with midnight placement typically strongest around May. From 52 degrees north its theoretical meridian altitude is about 0 degrees; local horizons and the live altitude chart determine the practical window.
Its brightness makes it a practical binocular or small-telescope candidate when it is well above the horizon.
What to expect
The SIMBAD classification for the matched source is OpC. A published radial velocity value is -20.4 km/s. The SIMBAD record currently connects it to 95 bibliographic references.
Its roughly 48.1 arcminute span suits a medium field of view. Use the listed 48.1 by 48.1 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
