JAM 1: Discovery of a New Candidate Evolved Planetary Nebula in Deep [O III] and Hα Imaging
We report the discovery of a previously uncatalogued extended emission nebula, hereafter JAM 1, detected in ultra-deep [O III] and Hα narrowband imaging. Located at 18 h56 m25 s, + 30 ° 42 ' 06 ″ (J2000), JAM 1 exhibits a nearly spherical morphology with an angular diameter of ≈864″ ( 14 . ' 4 ). The object is conspicuous in [O III], while in Hα it
