High Resolution Optical Imaging of Proto—Planetary Nebulae

Several Proto—Planetary Nebulae (PPN) candidates have been observed at the Canada France Hawaii Telescope with the High Resolution Camera (HRCam) (M c Clure et al. 1989, PASP, 101, 1156). Candidates were selected based on their IRAS [12]–[25] and [25]–[60] colors and their lack of variability. With HRCams’ small angular pixel size (0.13”/pixel) and active optics we achieved an average angular resolution of 0.65” in V and I waveband images.
