About West Veil Nebula

West Veil Nebula (C34) is catalogued as a supernova remnant in Cygnus. Its J2000 position is RA 20:45:38, Dec +30:43:00, corresponding to 311.4083 degrees RA and 30.7083 degrees Dec. The local catalogue places it about 2,500 light-years away. No consistent angular diameter is available in the source record.

Observing tips

StarWatchr rates this as a hard target at magnitude 7. It is associated with summer observing, with midnight placement typically strongest around July. From 52 degrees north its theoretical meridian altitude is about 68.7 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 ISM. The SIMBAD record currently connects it to 79 bibliographic references.

Confirm the framing in the live sky atlas before choosing a field of view. Use the listed unknown arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
