Abstract
In the course of a narrow-band imaging survey for dwarf emission-line galaxies in a nearby void, we serendipitously discovered a low-excitation nebula that fits the profile of a shell surrounding a low-temperature star. The star has a parallax of 0.47 ± 0.34 mas with a most likely distance of 1686 pc. It has apparent magnitudes in
r

and g of 18.5 and 19.54, absolute magnitudes
M
r

of 7.4 and 8.41, and a redshift of 140 km−1. The color and magnitude are consistent with a K6V dwarf. A lack of forbidden emission suggests that the nebular electron temperature is < 3500° K.
