The local catalogue places it about 57,000 light-years away. Its referenced angular extent is approximately 5.9 by 5.9 arcminutes.
Observing tips
This is rated as a moderate target at magnitude 8.9. It is associated with summer observing, with midnight placement typically strongest around July. From 52 degrees north its theoretical meridian altitude is about 45.4 degrees; local horizons and the live altitude chart determine the practical window.
A small telescope under reasonably dark skies is a good starting point; use the live altitude chart to choose its highest point.
What to expect
The SIMBAD classification for the matched source is GlC. A published radial velocity value is -406.1 km/s. The SIMBAD record currently connects it to 464 bibliographic references.
At roughly 5.9 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 5.9 by 5.9 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
