- Star Tales - Pictor (ianridpath.com)
One of the constellations representing technical and artistic apparatus introduced into the southern sky by the Frenchman Nicolas Louis de Lacaille after his observing expedition to the Cape of Good Hope in 1751–52. It lies under the keel of the now-dismembered Greek constellation Argo Navis, the ship of the Argonauts, next to the bright star Canopus. In fact the four brightest stars in Pictor, labelled α, β, γ, and δ by Lacaille, had been catalogued by the Dutch explorer Frederick de Houtman as part of Argo a century and half earlier.
- M-type star (Wikipedia)
Class M stars are by far the most common. About 76% of the main-sequence stars in the solar neighborhood are class M stars. However, class M main-sequence stars (red dwarfs) have such low luminosities that none are bright enough to be seen with the unaided eye, unless under exceptional conditions. The brightest-known M class main-sequence star is Lacaille 8760, class M0V, with magnitude 6.7 (the limiting magnitude for typical naked-eye visibility under good conditions being typically quoted as 6.5), and it is extremely unlikely that any brighter examples will be found.
