About NGC 7006
NGC 7006 (C42) is catalogued as a globular cluster in Delphinus. Its J2000 position is RA 21:01:30, Dec +16:11:15, corresponding to 315.3728 degrees RA and 16.1879 degrees Dec. The local catalogue places it about 135,000 light-years away. Its referenced angular extent is approximately 1.11 by 1.02 arcminutes.
Observing tips
This is rated as a very hard target at magnitude 10.6. It is associated with summer observing, with midnight placement typically strongest around August. From 52 degrees north its theoretical meridian altitude is about 54.2 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 -383.2 km/s. The SIMBAD record currently connects it to 566 bibliographic references.
At roughly 1.1 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 1.11 by 1.02 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
