The missing parts of Telescopium
The ghostly outline of Lacaille’s
original Telescopium can be traced into Sagittarius, Scorpius,
and Ophiuchus. The supporting mast extended northwards through
Corona Australis to the modern Eta Sagittarii, which was
Lacaille’s Beta Telescopii. The tube extended past the
curving tail of Scorpius and included G Scorpii
(Lacaille’s Gamma Telescopii, partly obscured here by a
globular cluster symbol), ending at 45 Ophiuchi (Theta
Telescopii), just north of the modern Scorpius–Ophiuchus
border.
