Caption: Figure 1.

Condor narrowband images of the area surrounding RS Oph in He II, [O III], He I, H α, [N II], and [S II] filters. RS Oph is marked with red ticks. Images have been 8 × 8 block-summed and are displayed with linear scaling. The RS Oph NSR is immediately apparent only in the Hα image as a nebulosity filling much of the field of view and bounded by a nearly 1 degree long linear feature running northeast to southwest at the southern edge of the image.
