About NGC 5694
NGC 5694 (C66) is catalogued as a globular cluster in Hydra. Its J2000 position is RA 14:39:36, Dec -26:32:19, corresponding to 219.9022 degrees RA and -26.5383 degrees Dec. The local catalogue places it about 113,000 light-years away. Its referenced angular extent is approximately 3.6 by 3.6 arcminutes.
Observing tips
StarWatchr rates this as a very hard target at magnitude 10.2. It is associated with spring observing, with midnight placement typically strongest around April. From 52 degrees north its theoretical meridian altitude is about 11.5 degrees; local horizons and the live altitude chart determine the practical window.
Because it is faint, use a larger aperture where possible, avoid bright Moon conditions, and use averted vision.
What to expect
The SIMBAD classification for the matched source is GlC. A published radial velocity value is -139.4 km/s. The SIMBAD record currently connects it to 328 bibliographic references.
At roughly 3.6 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 3.6 by 3.6 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
