It's finally going to be clear." I then focused back on my Uranometria.
* An engraving from Uranometria (1603)--the first star atlas to map both the northern and southern skies, published by Johannes Bayer.
The introduction then explains that the book is an effort to describe what the stars are actually like, something you don't get from such famous works as Norton's Star Atlas or Uranometria, for example.
Standards are the Pocket Sky Atlas (which shows stars to as faint as magnitude 7.6), the larger Sky Atlas 2000.0 (stars to magnitude 8.5), or better still, the even larger Uranometria 2000.0 (stars to magnitude 9.75).
It was the German astronomer Johann Bayer during the early 17th century, when he was producing his star atlas Uranometria, named after Urania, the Greek Muse of Astronomy.

Johann Bayer included many of these newly invented constellations in his epic star atlas Uranometria in 1603, and many, including all of the above, remain in use today.
His aim was to compare stars which were plotted on his copy of Gould's Uranometria Argentina (UA) (47) with the sky, with the aim of identifying new variable stars: 'Armed, then, with this work, we proceeded with youthful zeal to explore the region from 75[degrees]S.
Among the stars used to place the Hare's image in the sky, four of the faintest mark his ears as seen on our image of Lepus from Johann Bayer's unprecedented 1603 atlas, Uranometria. They are [iota], [kappa], [lambda], and v, and around them lie the deep-sky wonders for this month's sky tour.
As an example, he notes the inaccurate position and labelling of the galaxies NGC 5797 and NGC 5804 in Bootes as plotted in the Uranometria 2000 first edition.
In turn, de Gheyn's engraving style influenced Johann Bayer's magnificent pictorial atlas, Uranometria. In Syntagma Arateorum, a starry river-god personifies Eridanus, his waters spilling from an urn and swirling around him.
In his early years Markwick monitored variable stars with a field glass and searched for new variables by dividing up the equatorial and southern regions of the sky into 5[degrees] segments, examining them with binoculars and comparing them to the Uranometria Argentina.
