There are sections devoted to Ptolemy's constellations as well as "modern" constellations such as Microscopium
(the microscope), Fornax (the furnace) and Tucana (the toucan).
As a man of the Enlightenment and unencumbered by classical whimsy, he named most of his new constellations after, as he put it, "principal figures of the arts": The Painter's Easel; the Sculptor's Workshop; Microscopium
and Telescopium; Reticulum, the celestial apotheosis of his little refractor's measuring reticle; Octans, the Octant; Fornax, the Chemist's Furnace; and so on.
Lower still lies the small and insignificant Microscopium
. On a really clear evening it is worth trying to locate its brightest stars; gamma ([gamma]) at magnitude 4.67 and epsilon ([epsilon]) at 4.71 despite their being at an altitude of just over 6[degrees].
Hubble saw a ring around only one, HD 202628, which resides near the southern constellations Grus and Microscopium
Mirabile inquam; nam quod Telescopium in coelestibus corporibus ingentibus longo spatio dissitis, efficit, hoc idem in terrestribus corporibus minutissimis & prope oculos nostros efficit Microscopium
This mutual influence is seen most prominently in the language of the natural sciences (e.g., telescopium, microscopium
, acus nautica, etc.).
This season finds Ceres swinging from the southern tip of the Capricornus star pattern down through little-known Microscopium
and into easternmost Sagittarius.

At a press conference last week, researchers announced that the Hubble Space Telescope had detected such radiation from a Milky Way flare star called AU Microscopium
Only five other constellations--Caelum, Mensa, Microscopium
, Sextans, and Vulpecula--have a fainter lucida.
Farther south, 1 Ceres, the first-discovered and largest asteroid (diameter 850 kilometers), brightens past magnitude 8.0 in mid-July, reaches 7.6 at opposition in mid-August, and fades down past 8.6 in early October as it swoops from southern Aquarius through a corner of Piscis Austrinus into Microscopium
. And while you're here, check out the 7.5-magnitude globular cluster M30, which is paired with the 5.2-magnitude yellow star 41 Capricorni 0.4 to its east.
Some of them have been shortened, thankfully: Antlia (the Air Pump), Caelum (the Chisel), Circinus (the Drawing Compass), Fornax (the Furnace), Horologium (the Clock), Mensa (the Table, named for Table Mountain in South Africa), Microscopium
(the Microscope), Norma (the Square), Octans (the Octant), Pictor (the Painter's Easel), Pyxis (the Mariner's Compass), Reticulum (the Net), Sculptor (the Sculptor), and Telescopium (the Telescope).
