دانلود کتاب A Portfolio of Lunar Drawings (Practical Astronomy Handbooks)

Harold Hill's lunar portfolio is a unique collection of drawings now published for the first time. Each illustration is supplemented with notes made at the time of observation. Astronomical drawing still has an important place alongside photography in the same way that photography has not supplanted the artist in the fields of botany and ornithology, for example. Indeed, since astronomical images tend to shimmer because of turbulence in the Earth's atmosphere, drawings constructed by an artist who takes advantage of the fleeting moments of perfect vision are often more detailed than photographs. No one can fail to be impressed by the beauty and artistry of this work and, to the initiated, the accuracy and attention to detail is remarkable. This is a book for astronomers, amateur and professional alike, and for those who would simply like to know more about the moon.
