Ara is a Southern constellation, with its brightest star being Beta Arae. While the "Alpha (Constellation)" star is typically the brightest in that constellation, the ordering occasionally does not agree with modern measurements, as is the case with Ara. Interestingly, Ara contains Westerlund 1, which is a compact young super star cluster containing Westerlund 1 W26, one of the largest star known.
Ara is the 63rd largest constellation. Due to its smaller size, the author believes that it would be easier to locate Sargas in Scorpius, a star visible to the naked eye first. You can utilise that to pinpoint Ara, which resembles the letter "H", tracing the horizontal line in "H" from the two stars on Telescopium's side to the one star on Norma's.
This is a rough drawing of Ara, with its neighbouring constellations.
Westerlund 1 is a young massive open cluster which will eventually form a globular cluster. These clusters typically contain young stars which ionise the surrounding region, hence labelled "HII region". As star formation has usually taken place recently, a molecular cloud of partially ionized gas is created. For example, blue stars will emit large amounts of ultraviolet radiation which will ionise the surrounding gas. The HII region is then surrounded by a region of dust. Over millions of years, this region may produce thouands of stars. Westerlund 1 W26, a red supergiant, is calculated to be more than 1200 times the solar radii.
Up next is Aries.
