Observing tips
This is rated as an easy target at magnitude 6. It is associated with winter observing, with midnight placement typically strongest around January. From 52 degrees north its theoretical meridian altitude is about 14.1 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 21.7 km/s. The SIMBAD record currently connects it to 176 bibliographic references.
Its roughly 24.2 arcminute span suits a medium field of view. Use the listed 24.2 by 24.2 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
