What is "telescopium"

Telescopium is a minor constellation in the southern celestial hemisphere, one of twelve named in the 18th century by French astronomer Nicolas-Louis de Lacaille and one of several depicting scientific instruments. Its name is a Latinized form of the Greek word for telescope. Telescopium was later much reduced in size by Francis Baily and Benjamin Gould.

The brightest star in the constellation is Alpha Telescopii, a blue-white subgiant with an apparent magnitude of 3.5, followed by the orange giant star Zeta Telescopii at magnitude 4.1. Eta and PZ Telescopii are two young star systems with debris disks and brown dwarf companions. Telescopium hosts two unusual stars with very little hydrogen that are likely to be the result of two merged white dwarfs: PV Telescopii, also known as HD 168476, is a hot blue extreme helium star, while RS Telescopii is an R Coronae Borealis variable. RR Telescopii is a cataclysmic variable that brightened as a nova to magnitude 6 in 1948.

Telescopium is a genus of sea snails, marine gastropod mollusks in the family Potamididae. They are perfect cone-shaped shells

The modern constellation Telescopium lies across one of the quadrants symbolized by the The Black Tortoise of the North (北方玄武, Běi Fāng Xuán Wǔ), and The Southern Asterisms (近南極星區, Jìnnánjíxīngōu), that divide the sky in traditional Chinese uranography.

The name of the western constellation in modern Chinese is 望遠鏡座 (wàng yuǎn jìng zuò), meaning "the telescope constellation".
