Observing tips
This is rated as a moderate target at magnitude 8. It is associated with summer observing, with midnight placement typically strongest around June. From 52 degrees north its theoretical meridian altitude is about 28.6 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 OpC. A published radial velocity value is -10.2 km/s. The SIMBAD record currently connects it to 113 bibliographic references.
At roughly 7.1 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 7.1 by 7.1 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
