Extended Structures of Planetary Nebulae Detected in H\(_{2}\) Emission

We present narrow-band near-infrared images of a sample of 11 Galactic planetary nebulae (PNe) obtained in the molecular hydrogen (H\(_{2}\)) 2.122 \(\mu\)m and Br\(\gamma\) 2.166 \(\mu\)m emission lines and the \(K_{\rm c}\) 2.218 \(\mu\)m continuum. These images were collected with the Wide-field...
