Transit Date of principal star:
28 June

It is a shame that the most important instrument for astronomers should be associated with such a tiny portion of the sky, practically devoid of telescopic interest. Lacaille devised the constellation in the mid-eighteenth century.

Just east of the Scorpion's stinger lies the faint constellation of Corona Australis. To its south is found Telescopium. Its stars are mostly fourth and fifth magnitude.

Double stars in Telescopium:

This constellation has no outstanding binaries, and indeed all the visual binaries have rather faint primaries (sixth, seventh, or even eighth magnitude). For this reason none are listed.

Variable stars in Telescopium:

The brightest Mira-type variable is R Telescopii, which has a period of 462 days, and a range in magnitude of 7.8 to 14. The next maximum is expected in mid-March 1997; in 2000 the maximum should occur late in the year.

Deep Sky Objects in Telescopium:

The deep-sky objects in Telescopium -- mostly galaxies -- are all too faint for amateur study.
