This relatively bright planetary nebula in Pegasus is embedded in faint integrated flux nebula visible in this image catalogued as LBN152.
The central star of this nebula belongs to the class of PG 1159 stars - hydrogen-deficient post AGB-stars on their way to the white dwarf cooling sequence. However, a fraction of them shows small amounts of atmospheric hydrogen and are referred to as hybrid PG 1159 stars, which is the case for this object.
