Farnese Atlas
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.

Petrus Plancius
  • (15521622)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 "?aµ???p??da???" meaning "giraffe",
    from "??µ????" (kamelos), "camel" "p??da???"
    (pardalis), "leopard", due to its having a long
    neck like a camel and spots like a leopard.

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. 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.
  • ß 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 OS
    67 Camelopardalis with a greenish companion, 19
    Camelopardalis (probably an optical double), and
    S 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.

Can be seen in binoculars from country skies,

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
Kembles 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
25
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-2336gt
27
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.
28
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.
