The Trouvelot Astronomical Drawings Manual PDF Download

Excerpt from The Trouvelot Astronomical Drawings Manual During a study ofthe heavens, which has now been continued for more than fifteen years, I have made a large number of observations pertaining to physical astronomy, together with many original drawings representing the most interesting celestial Objects and phenomena. With a view to making these observations more generally useful, I was led, some years ago, to prepare, from this collection of draw ings, a series of astronomical pictures, which were intended to repre sent the celestial phenomena as they appear to a trained eye and to an experienced draughtsman through the great modern telescopes, provided with the most delicate instrumental appliances. Over two years were spent in the preparation of this series, which consisted of a number of large drawings executed in pastel. In 1876, these draw ings were displayed at the United States Centennial Exhibition at Philadelphia, forming a part of the Massachusetts exhibit, in the Department of Education and Science. The drawings forming the present series comprise only a part of those exhibited at Philadelphia; but, although fewer in number.
