There is not much to say about this member of the La Caille
constellation family: Mensa is located in the south polar region
of the sky. In this specific field one finds nearly no bright
stars (the brightest is of 5 mag) or other objects for note to
people using small telescopes.
The one object which is worth being mentioned is the part of the Large Magellanic Cloud which swaps into this constellation from ist northern neighbor Dorado.
The meteor shower Delta Mensids can be viewed from March 14 to March 21 with an hourly rate of 1 to 2 meteors. The maximum occurs at March 18. Detailed informations about the Delta Mensids can be found in Gary Kronks database about meteor showers.
