Observing tips
This is rated as a very easy target at magnitude 4.3. It is associated with autumn observing, with midnight placement typically strongest around October. From 52 degrees north its theoretical meridian altitude is about 84.9 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. A published radial velocity value is -62.2 km/s. The SIMBAD record currently connects it to 506 bibliographic references.
At roughly 16.3 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 16.3 by 16.3 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
