Image Details
Caption: Figure 1.
Illustrations of slit positions and orientations for our observations of the PNe M 1-11, Vy 2-2, and Hen 2-459 overlaid on archival HST WFPC2 F656N (Hα) images. Since Hen 2-459 was observed by nodding between two positions on the slit, the apparent slit length shown here is smaller than the actual IGRINS slit.
