New Planetary Nebulae Discovered by French Astrophotographs-Amateurs
Observatoire Astronomique de Strasbourg, France
Since 2012, French amateurs in astrophotography have been equipped with CCD imagers with high sensitivity and ∼1 arcsec resolution, allowing them to obtain images with high resolution and contrast, and with unprecedented depth, using narrow-band filters. On the other hand, they have been methodically scanning the digital sky survey (DSS), thereby visually identifying dozens of faint PN candidates in the Galaxy. These two methods lead to the discovery of 88 possible/probable PN. The large bipolar object Ou4 is one of the most interesting PN known.
