The large and older planetary nebula, PK 080-10.1, was just discovered in the 90s of the last century by Motch, Werner and Pakull (hence the name MWP, which was formed from the initials of the discoverers' names. When they examined a weak X-ray source in the swan. The X-ray source turned out to be the central star of a planetary nebula. The central star is not a normal white dwarf, but a pulsating star of the type GW Vir. GW Vir stars pulsate with periods of less than one hour through non-radial gravity waves.

NGC 7008 (PK 93+5.2), also known as the Fetus Nebula is a planetary nebula with a diameter of approximately 1 light-year located at a distance of 2800 light years in northern Cygnus. It was discovered by William Herschel in 1787, in Slough, England. NGC 7008 (H I-192) is included in the Astronomical League's Herschel 400 observing program.
