  Lacaille – Norma, Circinus, Triangulum Australe   (Site not responding. Last check: 2007-10-08)
Nicolas Louis de Lacaille depicted three southern constellations as a group of draughtsman’s instruments consisting of a set square and ruler (l’Equerre et la Regle, now known as Norma), a pair of compasses (Circinus), and a surveyor’s level (Triangulum Australe).
Norma and Circinus were Lacaille’s own inventions but Triangulum Australe was an earlier invention of Keyser and de Houtman which Lacaille adapted for the purpose.
The historian R. Allen mistakenly transferred the name “niveau” (meaning level) from Lacaille’s Triangulum Australe and applied it to Norma.

Triangulum Australe, or the austral triangle (TrA) is a small austral constellation located in the parallel of 70º of South, observable latitude solely in the South hemisphere during great part of the year and not in the north where I write these lines to you.
Triangulum Australe limits the north with the constellation of Norma, to the east with Circinus, the south with Apus and the west with Ara.

 Canberra Astronomical Society - Southern Cross - November 2000
In the NE of Aries, near the border with Triangulum, lies NGC 972 (2h 34.2m, +29 19'), an obliquely-inclined spiral almost twice as long (3.6') as it is wide.
The constellation of Triangulum is located on the NW side of Aries, and is also fairly small, consisting of a narrow triangle of 3rd and 4th mag.
The big feature of Triangulum is of course the large face-on spiral galaxy M33 (1h 33.9m, +30 39'), the third-largest galaxy in the local group.

Triangulum Australe and Circinus are circumpolar, that is never set, for places in New Zealand.

 Canberra Astronomical Society - Southern Cross - August 1996
Triangulum Australe, the Southern Triangle, is located east of Alpha Centauri, beyond the narrow constellation of Circinus.
I tried for the two brightest galaxies in the constellation, NGC 6156 (16h 34.7m, -59 36') and NGC 5938 (15h 36.6m, -66 50'), but they were not bright enough to see in my viewing conditions.
The remaining telescopic objects in Trianglum Australe are double stars.
