423pp + 390pp + 374pp + 396pp + 382pp VG/none vols 1 and 4 with small patches of slight discoloration on boards, minimal remains of paper label from dealer on endpapers, small and discreet stamps on title and content pages, last two pages in vol.1 (table of content) slightly creased not affecting text. Overall a very nice set. A cumulative index for the 5 volumes is included in vol. 5. Thorough and comprehensive work on optics and optical engineering and instruments with chapters written by specialists in the field. Content includes filters, optical materials, electro-optical devices, television optics, infrared detectors, microscopes, photographic objectives, still cameras, high-speed photography, astronomical telescopes etc.

In-4°, XX, pp.210, tavola fuori testo legatura in cartonato. Christian Kramp fu un astronomo, fisico e matematico francese, scrisse di vari argomenti e molti trattati di matematica pura. La sua opera principale benché di carattere astronomico è - Analyse des refractions astronomiques et terrestres - In questa opera affronta il problema della elasticità dell'aria in relazione alla sua densità ma soprattutto presenta una dettagliata tavola numerica delle funzioni trascendentali che cosi divenne importante nel CALCOLO DELLE PROBALITA' da essere chiamata " Kramp's trascendental", introdusse anche la funzione "n". Come Bessel, Legendre e Gauss egli estese la nozione di fattoriale ai sistemi di numeri non interi (non-whole). DSB ad vocem. In-4°, XX, pp.210, plate, cardboard binding Christian Kramp was a French astronomer, physicist and mathematician, he wrote of various and many subjects treatises on pure mathematics. His main work although of an astronomical nature is - Analyze des refractions astronomiques et terrestres - In this work he addresses the problem of air elasticity in relation to its density but above all it presents a detailed numerical table of transcendental functions which thus became important in the CALCULATION OF PROBALITIES to be called "Kramp's transcendental", also introduced the function "n". Like Bessel, Legendre and Gauss he extended the notion of factorial to non-whole number systems. (See DSB)

388 pages including bibliography and index. A unique technical handbook, bringing together topics that are generally not available to the non-specialist, bridging the gulf between novice and advanced astrophotographer. Includes detailed discussion of topics usually ignored in a general survey, such as photographic optics, instrument design, techniques at the telescope, films and developers, advanced darkroom methods, sensitometry and film hypersensitization. Emphasis is placed upon the understanding of basic photographic principles and on professional laboratory methods, encouraging readers to conduct their own experiments and make contributions to the science of photography. Chapters include: A Brief History of Astronomical Photography; Instrumentation; Techniques at the Telescope; Theoretical Points of Interest; Sensitometry; Black-and-White Photography; Color Photography; Introductory Darkroom Techniques; Advanced Darkroom Techniques; Hypersensitizing Techniques; Deep-Sky Astrophotography; High-Resolution Photography (including a selection of fine astronomical photography); Selected Topics; plus appendices. Moderate quantity of library markings. Front free endpaper removed. Only moderate wear. A solid copy with dust jacket in protective clear mylar cover. Book
