Menzel 1 , abbreviated Mz 1 , is a planetary nebula in the constellation Winkel Maß , which is about 3400 light years away.

The nebula was discovered in 1922 by Donald Menzel in photographs of the Bruce 24-inch telescope at the outstation of the Harvard College Observatory in Arequipa , Peru. Despite its comparatively high brightness, it has rarely been examined in more detail. One model explains its structure by projecting a three-dimensional hourglass- shaped shell with a density that decreases from the tailie to the poles. With a radial expansion speed of 23 km / s, its age is estimated at 4,500 to 10,000 years. The central star is assumed to be a white dwarf of 0.63 ± 0.05 M ⊙ .

Further published observations come from 1988, an H 2 emission at 2.12 µm, from 1992, using a line filter in H α and OIII, and from 2010, using the Spitzer space telescope at wavelengths from 3.6 µm to 8 µm.
