Planetary Nebula Minkowski 1-59
History
The planetary nebula was discovered in 1946 by the German-American astronomer Rudolph Minkowski. He was looking for H-α emissions on the photographic plates taken with the 60 inch or 100 inch telescope on Mount Wilson. [397]
Physical Properties
M 1-59 is a bi- or multipolar planetary nebula with at least three pairs of closed-end bipolar lobes and a hollow shell in the center. The kinematic age is estimated to 4050 years. The photometric magnitudes through different filters are: J 12.328; H 12.205; K 11.225. Given distances range from 1.2 kpc to 5.5 kpc. [145, 613]

The planetary nebula Minkowski 1-59 is located in the constellation Scutum, circa 0.5° east of the 4.7 mag bright star δ Scuti and about a quarter towards the open cluster Messier 26.
Visual Observation
400 mm Aperture: In the 21 mm Tele Vue Ethos (85x) the PN appears as a small dot among stars. In the 9 mm Nagler, the dot is slightly larger but hardly more than a star. — 400 mm f/4.5 Taurus Dobsonian, Gurnigel, 19. 8. 2023, Bernd Nies
