on the N edge of the PN is shown in Figure 12. The predominant features are and emission lines, and low level continuum emission which is probably reflected from the central star.

### IC 4593

Bohigas & Olguin (1996) obtained spectroscopy and imaging of this PN which has two inner shells surrounded by an outer highly excited halo. IC 4593 is unusual in that the condensations outside of the inner region are located asymmetrically in the SW region.

Two spectra were taken on this PN, one positioned on the central star, and the other at a position 3 E (Figure 12). The core shows bright stellar continuum, with nebular lines superimposed, and  absorption. The E spectrum has the typical and emission lines. The sky subtraction was not of high quality for this spectrum, which resulted in OH airglow lines showing up in emission in the H and K spectral regions.

### J 320

Images of J 320 (Balick 1987) show it to have a central region that is elongated roughly E-W, but the low level flux has a N-S elongation indicating a shell or streamer extending in this direction. Three spectra for J 320 are shown in Figure 13, centered
