摘要：
H alpha and [O III] narrow-band, wide-field (7 x 7 deg(2)), CCD images of the Small Magellanic Cloud were compared, and a catalogue of candidate planetary nebulae and H alpha emission-line stars was compiled. The catalogue contains 131 planetary nebulae candidates, 23 of which are already known to be or are probable planetary nebulae or very low excitation objects. Also, 218 emission-line candidates have been identified, with 113 already known. Our catalogue therefore provides a useful supplement to those of Meyssonnier & Azzopardi and Sanduleak, MacConnell & Davis Phillip. Further observations are required to confirm the identity of the unknown objects.
