	Henry Draper Summary
		Draper's father, John William Draper, was an accomplished doctor, chemist, and professor at New York University; he was also the first to photograph the moon through a telescope in the winter of 1839-1840.
		Draper's mother was Antonia Coetana de Paiva Pereira Gardner, daughter of the personal physician to the Emperor of Brazil.
		Draper was one of the pioneers of the use of astrophotography.

	Henry Draper Biography
		John William Draper was greatly interested in the chemical effects of light; among other accomplishments, he took the first daguerreotype of the Moon in the winter of 1839-1840 and one of the first human portraits in 1840.
		Draper was married in 1867 to Anna Mary Palmer, a wealthy socialite who proved as able a laboratory assistant as she was a hostess.
		Draper received numerous awards, including honorary law degrees from NYU and the University of Wisconsin, a Congressional medal for directing the U.S. expedition to photograph the 1874 transit of Venus, and election to both the National Academy of Sciences and the Astronomische Gesellschaft.

		Henry Draper, a wealthy amateur astronomer, left a very generous bequest to the Harvard College Observatory.
		The resulting Henry Draper Catalog of Stellar Spectra remains one of the most important sources of information on stars, a century after its creation.
		For example, the first extrasolar planet detected by the transit method circles the star HD 209458, which is number 209,458 in the Henry Draper Catalog.

		For example, using the "Guide Star Catalog" (stars to magnitude 15) to draw a chart of constellation Cygnus is not practical.
		It is easy to select the catalog to use for a selected viewing field and to limit the magnitude of the objects.
		This catalog is an extraction of 54,787,624 stars from USNO-A principally from magnitude 16 to 19.

	The HYG Database \| The Astronomy Nexus
		The database is a subset of the data in three major catalogs: the Hipparcos Catalog,the Yale Bright Star Catalog (5th Edition), and the Gliese Catalog of Nearby Stars (3rd Edition).
		The Gliese catalog is the most comprehensive catalog of nearby stars (those within 75 light years of the Sun).
		By contrast the Gliese catalog breaks all known multiple stars, excluding those too close to be separated optically, into their components, and gives each one a magnitude.

		Near the turn of the century, Cannon began working on a project began by Henry Draper, to classify all the stellar spectra that could be obtained with a modest-sized objective prism instrument.
		Although Draper died before the project was very far underway, Draper's widow sponsored its continuation, eventually published as the Henry Draper Catalog.
		This was followed by the Henry Draper Extension, bringing the total number classified to one-third of a million.

	HENRY DRAPER star catalog, edition 1985
		Begun in the early 1900s, the intent of the catalog was to provide spectral classifications of all stars down to the faintest possible magnitude limits of the object-prism plates available at the time.
		The catalog was subsequently extended to fainter stars in selected areas of the sky.
		This object is marked as a "nebula" in the HD catalog.

		Somewhere in a survey’s or catalog’s description there is usually a discussion of the precision of its data.
		Henry Draper catalog was one of the first catalogs of spectra of all the stars in the sky.
		Naval Observatory (USNO) catalogs (which are widely used for finder charts) also contain photographic magnitudes in B, R and sometimes I. They are mainly positional data and are from Palomar Observatory Sky Survey (POSS) plates which have been scanned.

	Star Catalogs
		Early discoveries involving star catalogs include the precession of the equinoxes, a consequence of the precession of Earth's axis in roughly 26,000 years.
		In this catalog, which contained lots of errors and was never authorized by Flamsteed, stars in each constellation were numbered by the so-called Flamsteed numbers, in the order of Right Ascension.
		When spectroscopy came up in the second half of the 19th century, spectral classifications and catalogs of stars were compiled, one of the first lists being that of the Italian Father Angelo Secchi (1818-1878), which appeared in 1867 and contained 316 stars.

		The catalog number was assigned by counting stars in declination (the north-south celestial coordinate) zones.
		It goes as faint as about 13th magnitude (but is incomplete for stars that the faint), and does not include the brightest stars (which were overexposed on the photographs which were measured), and stars which overlapped on the photographs.
		Catalogs of stars have been made giving new data such as proper motion or position or spectral type.

		However, interest may focus on a particular subset of stars, and the Star Filter panel on the Chart Settings - Stars tab allows a subset to be specified by the user in different ways.
		A completely general way of defining a subset of the Catalog is the 'selection set', which is simply the set of stars which has been explictly selected by the user, e.g.
		Sort by [attribute] - sorts the catalog using the data of the attribute column.

		And, worse for the peruser of astronomical literature, almost all star catalogs overlapped each other, so that a star identified as 95735 in the Henry Draper catalog is the same object as number 21185 in the Lalande catalog.
		The only way to pin down a given star, then, is to give its right-ascention and declination in a given year (or "epoch") out to the greatest accuracy possible, and use that as your reference point when looking into the various catalogs.
		Note that variable stars have their own naming convention which, while being somewhat convoluted, is at least consistent across the astronomical community.

	How Astronomical Objects Are Named
		The most commonly seen are the Smithsonian Astrophysical Observatory catalog, the Henry Draper catalog and Aiken’s catalog of double stars, however a number of others are use.
		The earliest catalog that is still in wide use is the Messier catalog which includes 110 objects, they are usually referred by a letter M followed by a number (for example M31 is the andromeda galaxy).
		Objects in these catalogs are indicated by the letters NGC or IC followed by a number (for example NGC 7000 is the North American Nebula).

	Temperature of the Hottest Star
		Stars are divided into seven broad groups by the system of spectral classification known as the Henry Draper Catalog.
		These stars are not included in the Henry Draper Catalog because of their different chemical composition.
		One example is the Alpha Percy; it would be classified as H5 Id, which means that it falls about halfway between the beginnings of type F and type G. The Id suffix means that it is a particularly luminous star.

		The Henry Draper Catalogue is an astronomy catalogue with astrometric and spectroscopic data about more than 225,000 of the brightest stars visible from the northern hemisphere.
		It was compiled by Annie Jump Cannon and her female co-workers at Harvard College Observatory under the supervision of Edward C. Pickering, and was named in honour of Henry Draper, whose widow donated the money required to finance it.
		Stars in the range 225301-359083 are from the 1949 extension of the catalogue.
