Légende du diagramme : The constellation Dorado with its bright stars and surrounding constellations. Dorado is surrounded by (going clockwise from the top): Pictor, Caelum, Horologium, Reticulum, Hydrus, Mensa and Volans.

Dorado is a southern constellation and thus the whole constellation is visible at some point in the year from the whole southern hemisphere. The whole constellation is also visible to equatorial regions of the northern hemisphere. Dorado is circumpolar for temperate and antarctic regions of the southern hemisphere. This constellation is best viewed in the northern hemisphere winter and southern hemisphere summer.

The Large Magellanic Cloud (LMC), a satellite galaxy of the Milky Way, lies in Dorado and the neighboring constellation Mensa. The outline of the Large Magellanic Cloud is marked here as a roughly circular loop in green. The open cluster NGC 2070 lies at the heart of the Tarantula Nebula. This is marked here with a green square.

The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.
