(Left) TNG and NTT J (blue), H (green), and K_S (red) composite pictures and (right) IR spectral energy distributions (SEDs) of the IRAS post-AGB star and PN candidates. In the pictures, north is up, east to the left. The field of view is 1′, but for IRAS 05573 + 3156 and IRAS 06499 + 0145 which is 15. The SEDs are built using our JHK photometric measurements and data extracted from the Spitzer GLIMPSE, MSX, AKARI, and IRAS catalogs. The arrows at J, H, K, or 100 μm represent flux upper limits (in the case of 100 μm, IRAS quality-factor, FQUAL, equals to 1).
