    Intro and Visual description

    Locate Canopus by drawing a line from the easternmost star of Orion’s belt down through Rigel, Orion’s left foot. Canopus lies about twice as far from Orion’s belt as Sirius.

    Between Canopus and the south pole lies the Large Magellenic Cloud (LMC), located in the constellation Dorado the Swordfish.

    Between Canopus and Crux are the False Cross (nearer Canopus, shared by Carina and Vela) and the Diamond Cross (nearer Crux, in Carina). These are fainter than Crux and were once part of Argo Navis.

    Intro and Visual description

    When looking for the Southern Cross, beware of two similar asterisms nearby, both of which point more toward the Large Magellenic Cloud (in the constellation Dorado) than toward the south celestial pole: 

    1. The Diamond Cross (in Carina).
    2. The False Cross (between Carina and Vela).

    The real Crux has two unmistakable marks, which will help you be sure you’ve found the real thing:

  • Leo - Leo the Lion

    Intro and Visual description

    East of the Gemini twins lies Leo the Lion.

    Find the bowl of the Big Dipper. A line running through the two stars of the bowl of the Big Dipper on the side nearest the handle points almost directly to two other notable stars. Follow them below the bowl of the Dipper to Regulus.

    Leo’s mane looks like a backward question mark, or sickle. Regulus, the "dot" at the bottom of the mark, lies nearly on the ecliptic.

    His flank is a triangle of stars farther east.
