Discovery of Faint Nebulosity around a Z Camelopardalis–type Cataclysmic Variable in Antlia: Nova Shell or Ancient Planetary Nebula?

We report our discovery of a faint nebula surrounding a previously little-studied 15th mag variable star, ASASSN-19ds, in the Southern Hemisphere constellation Antlia.
