WeSb 3 with PaEl 4
In the upper left quadrant we have WeSb 3, a 51 arc sec planetary nebula discovered by Ronald Weinberger and Franco Sabbadin. The outer structures around the planetary nebula were discovered by the Galactic Planetary Nebula Halo Survey (GPNHS) team in January 2015.
Nearby in the lower right quadrant we have the first high-resolution image of 42 arc sec likely planetary nebula PaEl 4 discovered earlier this year by my good friend Dana Patchick and David Elmore.
