Digitizing the Harvard Observatory Plate Collection
Digitizing the Harvard Observatory Plate Collection Scanning the “Historic Sky” Our Goals: Find Funding to Construct a Scanner and Digitize the Harvard Astronomical Photographic Plate Collection. Make the results available in Online Storage. Jonathan E. Grindlay – Harvard Professor of Astronomy Elizabeth Griffin – WG Chair IAU Digitization and Preservation Alison Doane – Acting Curator of the Harvard Plate Stack Douglas J. Mink - Software and Data Archivist Bob Simcoe – Volunteer Associate & System designer Before photography, astronomers’ eyes were their only sensing device and hand drawing was the means of permanent recording. This severely limited the science they could accomplish. rjs Astronomy, as a science, made quantum leaps forward with the advent of photography. For the first time permanent, measurable photographic records made possible “offline” analysis of data. rjs The first daguerreotype of the moon was made by American physiologist J.W. Draper in 1840, involving a full 20 minute exposure. The first star was not recorded until 1850, when director of Harvard Observatory, W.C. Bond and Boston photographer J.A. Whipple, took a daguerreotype of Vega. The first photographic sky surveys were done at Harvard during the period of 1882-1886. Each photograph covered 15 degree squares of sky and recorded stars as faint as 8th magnitude. rjs The world’s collection of astronomical photographic images (estimated at 2 million glass plates) represents the costly output of over a century of devotion and skill by myriad astronomers. Harvard Observatory now has 500,000+ photographs, by far the largest collection and 25% of the world’s total. Harvard’s plates contain the most complete sky coverage of both the northern and southern sky over the longest time period – 1880 to 1989 rjs Since the 1980’s, astronomers have largely abandoned the use of photography. -

Imaging and Imaging Detectors
4–1 Imaging and Imaging Detectors 4–2 Introduction Detectors we have dealt with so far: non-imaging detectors. This lecture: imaging optical photons and X-rays Any imaging system has two parts: 1. Imaging optics In most applications, mirrors are used for imaging, although other techniques (variants of shadow cameras) are used, e.g., for γ-rays 2. Spatially resolved detector i.e., a detector capable of measuring where a photon hits it in the focal plane. This can be a photographic plate or film, but is normally a charge coupled device (CCD). Introduction 1 4–3 Optical Imaging, I Cassegrain telescope, after Wikipedia Reminder: Optical telescopes are usually reflectors: primary mirror secondary mirror detector → → Main characteristics of a telescope: collecting area (i.e., open area of telescope, πd2/4, where d: telescope diameter) • ∼ fpr small telescopes: angular resolution, • λ θ = 1.22 (4.1) d but do not forget the seeing! Imaging 1 4–4 Optical Imaging, II Optical telescopes are based on principle that reflection “just works” with metallic surfaces. For X-rays, things are more complicated... Snell’s law of refraction: sin α n α1 n2 1 1 = = n (4.2) sin α2 n1 θ where n index of refraction, and α1,2 angle wrt. 1 surface normal. If n 1: Total internal reflection Total reflection occurs for α2 = 90◦, i.e. for n < n α 2 1 sin α1,c = n cos θc = n (4.3) 2 ⇐⇒ with the critical angle θ = π/2 α . c − 1,c Clearly, total reflection is only possible for n< 1 Light in glass at glass/air interface: n = 1/1.6 = θc 50◦ = principle behind optical fibers. -
Big Bertha/Baby Bertha
Big Bertha /Baby Bertha by Daniel W. Fromm Contents 1 Big Bertha As She Was Spoke 1 2 Dreaming of a Baby Bertha 5 3 Baby Bertha conceived 8 4 Baby Bertha’s gestation 8 5 Baby cuts her teeth - solve one problem, find another – and final catastrophe 17 6 Building Baby Bertha around a 2x3 Cambo SC reconsidered 23 7 Mistakes/good decisions 23 8 What was rescued from the wreckage: 24 1 Big Bertha As She Was Spoke American sports photographers used to shoot sporting events, e.g., baseball games, with specially made fixed lens Single Lens Reflex (SLR) cameras. These were made by fitting a Graflex SLR with a long lens - 20" to 60" - and a suitable focusing mechanism. They shot 4x5 or 5x7, were quite heavy. One such camera made by Graflex is figured in the first edition of Graphic Graflex Photography. Another, used by the Fort Worth, Texas, Star-Telegram, can be seen at http://www.lurvely.com/photo/6176270759/FWST_Big_Bertha_Graflex/ and http://www.flickr.com/photos/21211119@N03/6176270759 Long lens SLRs that incorporate a Graflex are often called "Big Berthas" but the name isn’t applied consistently. For example, there’s a 4x5 Bertha in the George Eastman House collection (http://geh.org/fm/mees/htmlsrc/mG736700011_ful.html) identified as a "Little Bertha." "Big Bertha" has also been applied to regular production Graflexes, e.g., a 5x7 Press Graflex (http://www.mcmahanphoto.com/lc380.html ) and a 4x5 Graflex that I can’t identify (http://www.avlispub.com/garage/apollo_1_launch.htm). These cameras lack the usual Bertha attributes of long lens, usually but not always a telephoto, and rapid focusing. -

"MAKE THE CORRECTION ON THE NEGATIVE" DOUBLE SWING BACK DOUBLE SWING FRONT lhe STANDARD COMMERCIAL SERIES /or extra large rigid cameras, extra long bellows for extra long focus lenses permitting greatest possible image control, greatest possible depth of field control at the largest possible " taking aperture". extra tall rigid camera stands, permitting highest elevation at maximum angle positions for look-down reproductions. Also allowing lowest maximum angle position for look-up reproductions. L. F. DEARDORFF & SONS, INC. H SOUTH DES PLAINES STREET, CHICAGO 6, ILLINOIS DESIGNERS AND BUILDERS OF PRECISION CAMERAS AND STANDS FOR CORRECTIVE PHOTOGRAPHY COMMERCIAL SERIES CAMERAS This series of Commercial Studio Cameras made for many years has always led the field in perfection of design, compactness, rigidity and ease of manipulation for making the most perfect reproductions. Throughout the world the leading Commercial, Illustrative and Industrial Photographers not only welcomed this series of cameras but proclaimed them the Standard of perfection in their field. The extra size of this series and the extreme double swings at the back and front and the raising, lowering and sliding lens board permit making repro ductions of the desired size, showing detail and sharpness of definition, with depth of field control, perspective control, and last but not least image distortion control not possible with the smaller view type of cameras. The use of extra long focus lenses permits making the desired size of image from the correct point of view of even the smallest objects. Freedom from distortion plus superior lighting effects, made pos sible because of the greater lens to subject distance, has greatly improved the work of the illustrator as is seen from a study of the results coming from many outside sources. -
Some Applications of Natural Color Photography in Mineralogy B
SOME APPLICATIONS OF NATURAL COLOR PHOTOGRAPHY IN MINERALOGY B. M. Snaus, Smith College,Northampton, Massachusetts. The use of natural color photographs or color transparenciesl in mineralogy and petrography is still in the initial stage of application, although hand-colored lantern slides have, for a long time, been em- ployed by teachers and lecturers on these subjects. During the past decade improvements have been made in the art of color photography, and at present there are several good color plates on the market. These are known as screenplates. In one type the color elements,red, green and blue-violet, are incorporated in an irregular mosaic forming a color screen, which is placed between the glass plate or film and the photo- graphic emulsion. In another type the color screen involves a separate plate consisting of a regular pattern of square or other ruled elements having the same colors in a gelatin coating. The former is known as a combination screenplate, or film, of which the Lumiere Autochrome film and the Agfa color plate are examples; the latter are referred to as sepa- rate screen plates, and the well known Finlay color plate is the out- standing example. The production of a positive picture on a combination plate involves a comparatively simple reversing process,during the finishing operations. With the separate screen plate a negative is made on a separate pan- chromatic plate which is exposed while pressedin contact, emulsion to t'taking emulsion, with a color screen known as the screen." The glass side of the latter is held towards the lens. -
