Phantom Streak Nebula
Scientific overview
Phantom Streak Nebula is a planetary nebula in the constellation Aquila. It shines at apparent magnitude 11.5 and spans about 0.13 arcminutes of sky.
Observation guide
Guidance follows standard observing practice, derived from the object's real magnitude and position. A dark, moonless sky always helps.

Physical size is derived from the OpenNGC angular size and the catalogued distance (small-angle: size = angle × distance). This is a Galactic object: its Doppler shift is shown as a radial velocity, not a cosmological redshift. Fields a source did not provide are omitted, never invented.
