During a program to discover new YSO candidates [1], we have serendipitously discovered IRAS 17340-3757 to be a hitherto unknown carbon star with unique properties. The central star is surrounded by a strikingly symmetric, bipolar, reflection nebula, visible at optical and near-infrared wavelengths. Mid-infrared imaging and spectroscopy show that the central point-source possesses a large infrared excess. Optical spectroscopy reveals the central source to be a highly reddened J-type (i.e. 13C-rich) Carbon star. Curiously enough, we also observe O I in absorption in the optical spectrum of the central source [4].
