The planetary nebula M94--20 in the Large Magellanic Cloud wasserendipitously observed with the Space Telescope Imaging Spectrograph on boardthe Hubble Space Telescope as part of the Hubble Space Telescope Archival PureParallel Program. We present spatially resolved imaging and spectral data ofthe nebula and compare them with ground based data, including detection ofseveral emission lines from the nebula and the detection of the central star.We find the total H alpha + [NII] flux = 7.3e-15 erg s^-1 cm^-2 and we estimatethe magnitude of the central star to be m_V = 26.0 +/- 0.2. Many other H alphasources have been found in M31, M33 and NGC 205 as well. We discuss the use ofthe parallel observations as a versatile tool for planetary nebula surveys andfor other fields of astronomical research.Comment: Latex, 14 pages, 2 JPEG figures, 2 tables.
