The celestial sphere carried by Atlas on his back is the oldest depiction of the sky as the ancients saw it. The globe features the celestial equator, the ecliptic with the zodiac band, the Arctic and Antarctic circles, the colure and the constellations (19 northern, 14 southern) with the 12 signs of the zodiac.

(1552–1622) Dutch cartographer and constellation inventor. A Plancius globe of 1612 introduced Camelopardalis and Monoceros, along with others in both hemispheres that never gained acceptance: Jordan, Tigris, Apes (Musca Borealis), Gallus, Cancer Minor, and Sagitta Australe.

Camelopardalis Coined in English 1785, the word camelopardalis comes from the Latin and it is the romanisation of the Greek "καμηλοπάρδαλις" meaning "giraffe", from "κάμηλος" (kamēlos), "camel"+ "πάρδαλις" (pardalis), "leopard", due to its having a long neck like a camel and spots like a leopard. romanisation
Jacob Bartsch (Jacobus Bartschius ) (c. 1600 – 26 December 1633) German astronomer. Usus Astronomicus Planisphaerii Stellati Argentoratum (Strasburgo) 1624 Bartsch married Johannes Kepler's daughter Susanna on 12 March 1630 and helped Kepler with his calculations. After Kepler's death in 1630, Bartsch edited Kepler's posthumous work Somnium. He also helped gather money from Kepler's estate for his widow.Somnium Bartsch died in Lauban in 1633.

Quick Facts Although Camelopardalis is the 18th largest constellation, (757 sq. deg. ) it is not a particularly bright constellation, as the brightest stars are only of fourth magnitude. β Camelopardalis is the brightest star, at apparent magnitude 4.03. This star is a double star, with components of magnitudes 4.0 and 7.4. The second brightest is CS Camelopardalis, which has neither a Bayer nor a Flamsteed designation. It is of magnitude 4.21 and is slightly variable. Other double stars interesting to amateurs are OΣ 67 Camelopardalis with a greenish companion, 19 Camelopardalis (probably an optical double), and Σ 1694 Camelopardalis (a blue and yellow optical double). Other variable stars are U Camelopardalis, VZ Camelopardalis, and Mira variables T Camelopardalis, X Camelopardalis, and R Camelopardalis.

NGC-2403 Can be seen in binoculars from country skies, sometimes fools comet hunters. NGC 2403 possesses about 100 emission regions as well as 27 variable stars. Larger instruments will reveal many of these regions that seem to take on likeliness to M33. Three supernovae have been spotted in this galaxy, one in 1954 (SN 1954J) with the others, a half a century later in 2002 (SN 2002kg) and in 2004 (SN 2004DJ).

NGC 1502 listed at magnitude 5.7 and contains about 15 stars including a couple of doubles names Struve 484 and Struve 485. NGC 1502 is also one end of Kemble’s Cascade. This string of stars might seem to be from the same group but the Cascade is only a chance lineup of varying distant suns.

The Giraffe is home to 53 NGC objects, most of which are galaxies
NGC-1501 (Oyster Nebula ) Magnitude 14.5 Wolf- Rayet star is embedded in a bluish halo. At 4,800 ly away NGC 1501 is more than four times farther and 3 times larger than the famous Ring Nebula.
NGC- 2336 Well structured galaxy with numerous delicate arms. It is listed as magnitude 10.9 and rests some 110 million ly away. NGC 2336 does have the distinction of being the northern most galaxy closest to Polaris.
NGC-2715 Tilted galaxy with detailed arm structure. This SBc galaxy glows at magnitude 11.4. NGC 2715 measures 5 arc minutes of sky and is an estimated 62 million ly away.
