    You can find detailed knowledge about these faint nebulas there.

    Ou4 is dicovered in august 2011 by an amateur named Nicolas Outters.
    Its only visible in [OIII]. The nature of this very faint nebula is still not known. Maybe it's a planetary nebula. The distance and the central star are also not known.
