Fig. 2


Two-color images of IC 63 (top panels) and IC 59 (bottom panels). The figures show a comparison between the Hα emission (in green) from the INT-WFC Photometric Hα Survey of the northern Galactic plane (IPHAS; Drew et al. 2005; Barentsen et al. 2014), and the IRAC 8 μm image taken with Spitzer (in red, right column), and the PACS 160 μm image takenwith Herschel (in red, left column). The regions covered by IRS spectral data are shown for both nebulae. For IC 59 we have also added the fields observed with SOFIA in the two runs (white rectangles aligned parallel to the declination axis).
