This book was written to be intelligible to general readers while also containing facts and figures useful to amateur astronomers at the time of its first printing in 1891. With the aid of many illustrations and the passionate wonder felt by astronomers of all levels and times, the author outlines the evolution of the telescope to the end of the nineteenth century and provides detailed instruction that is relevant and rich in historical value. No matter how humble the observer, or how paltry the telescope, astronomy is capable of furnishing an endless store of delight to its adherents. Its influences are elevating, and many of its features possess the charms of novelty as well as mystery. Whoever contemplates the heavens with the right spirit reaps both pleasure and profit, and many amateurs find a welcome relaxation to the cares of business in the companionship of their telescopes on "starlight evenings."
