Narrow-band Hα, [N II], and [O III] images of Me 2-1. Left column: Original images. Intensity levels and contours are logarithmic. Contours are separated by a factor of 2^1/2 in linear intensity. Right column: Deconvolved images denoted with (d) after the filter’s name. Intensity levels are linear. The elliptical ring, the SE and NW caps, and the PS knots in the caps (see text) are labeled in the [N II](d) image. For the labels of the caps and bright knots, blue and red colors are used for blueshifted and redshifted features with respect to the systemic velocity of the nebula. Orientation and spatial scale are identical in the six panels and indicated in the [O III] image (bottom left).
