Illustrated Descriptive Catalogue Of Achromatic Microscopes Telescopes Opera Race And Field Glasses And Other Optical Philosophical Mathematical Surveying And Standard Meteorological Instruments Classic Reprint

Excerpt from Illustrated Descriptive Catalogue of Achromatic Microscopes, Telescopes, Opera, Race and Field Glasses, and Other Optical, Philosophical, Mathematical, Surveying, and Standard Meteorological Instruments Though the following pages are intended to supply the place of a Catalogue only, it will be found, on careful perusal, that they contain much useful information and descriptive explanation, necessary for the amateur and student in the selection of any particular instrument or apparatus, and which I hope will make this little work more acceptable to my numerous and kind patrons than a mere Price List. Being a practical working optician and scientific instrument maker, assisted by the most skilled and experienced workmen, I can confidently assert that the best class work only is made in my establishment and having the advantage of extensive workshops on the premises, under my own superintendence, I can undertake. To execute any order to satisfaction and with despatch. The Microscope has always formed a special branch of my business, the improvement of which, with its accessory apparatus and object glasses, occupies my constant care and attention: a few extracts which I append, from several authors of standard works on the Microscope, will amply testify this assertion.

Commercially-made astronomical telescopes are better and less expensive than ever before, and their optical and mechanical performance can be superb. When a good-quality telescope fails to perform as well as it might, the reason is quite probably that it needs a little care and attention! Here is a complete guide for anyone who wants to understand more than just the basics of astronomical telescopes and accessories, and how to maintain them in the peak of condition. The latest on safely adjusting, cleaning, and maintaining your equipment is combined with thoroughly updated methods from the old masters. Here, too, are details of choosing new and used optics and accessories, along with enhancements you can make to extend their versatility and useful lifetime. This book is for you. Really. Looking after an astronomical telescope isn’t only for the experts - although there are some things that only an expert should attempt - and every serious amateur astronomer will find invaluable information here, gleaned from Barlow Pepin's many years’ experience working with optical instruments.

Classic telescopes are of interest to amateur astronomers for a variety of reasons. There are the dedicated collectors, but there are also many amateurs who love the nostalgia they inspire. These telescopes "feel" different from any contemporary telescope and perhaps have a unique ability to reconnect the owner to a bygone age of craftmanship. This book takes a look at traditional telescopes built by the great instrument makers of the 18th and 19th centuries, particularly the dynastic telescope makers, including Dollond, Alvan Clark, Thomas Cooke & Sons, and Carl Zeiss. Also included are lesser luminaries such as John Brashear, John Calver, William Wray, Henry Fitz, and William Henry Mogey. 'Classic Telescopes' covers the key features of the telescopes designed by these manufacturers, and shows how a heady combination of market trends, instrument condition, and pedigree will dictate their prices at auction. 'Classic Telescopes' also shows the reader how to find real bargains! Interviews with top classic telescope collectors (and users) provide the best tips of prospecting for a genuine acquisition.
