(a) WISE false color image of the Pa 30 nebula where blue and green stand for 11 μm emission, and red for 22 μm; (b) in this false color image, where green stands for WISE 11 μm (as in the left panel) and red for WISE 22 μm (adjusted to show extended emission), the emission from the central star is highlighted in blue from the GALEX near-UV data, while the XMM-Newton contors show that the majority of the X-ray emission originates from the core of the nebula; a background point source is seen westward of the CS in the XMM-Newton contour map; (c) the 2.1 m KPNO image; the green cross in the center of the image marks the location of the CS; panels (a)-(c) are reproduced at the same angular scale and orientation; at the Gaia distance of Pa 30 of 2,300 parsecs, an angular scale of 45'' translates to about 100,000 AU.
