Observing tips
StarWatchr rates this as a hard target at magnitude 6.8. It is associated with spring observing, with midnight placement typically strongest around April. From 52 degrees north its theoretical meridian altitude is about 0 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 BLL. SIMBAD records the morphology as S0pec. A published radial velocity value is 562.2 km/s. The SIMBAD record currently connects it to 4820 bibliographic references.
Its roughly 25.7 arcminute span suits a medium field of view. Use the listed 25.7 by 17.78 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
