About Lagoon Nebula
Lagoon Nebula (M8) is catalogued as a diffuse nebula in Sagittarius. Its J2000 position is RA 18:03:41.27, Dec -24:22:48.6, corresponding to 270.9042 degrees RA and -24.3867 degrees Dec. The local catalogue places it about 5,200 light-years away. Its referenced angular extent is approximately 90 by 40 arcminutes.
Observing tips
StarWatchr rates this as a moderate target at magnitude 6. It is associated with summer observing, with midnight placement typically strongest around June. From 52 degrees north its theoretical meridian altitude is about 13.6 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. The SIMBAD record currently connects it to 650 bibliographic references.
At roughly 90 arcminutes across, it favors a wide-field imaging setup. Use the listed 90 by 40 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
