Description: | "A set of very high resolution (i.e. fine detail) glass photographic plates, 14 inches (355 mm) square, 7 copies of original 48-inch (1.22 m) Schmidt telescope plates from the UK Schmidt Telescope's Southern sky survey; 3 from the 48-inch Palomar Schmidt Telescope's Northern sky survey. These are effectively sub-master plates but are 'seconds'; they may have minor blemishes visible only to an expert. They are very fragile and represent almost raw astronomical data or the nearest most people get to a traditional raw astronomical photographic image. The plates need to be viewed through a large light-box, with a magnifier of at least x10 on hand to see the detail. Each plate is kept in a custom, marked, envelope. THE PLATES SHOULD ON NO ACCOUNT TO BE HANDLED WITHOUT CLEAN GLOVES. The set was a gift from the Royal Observatory Edinburgh and is kept in its original yellow photographic box. Each plate weighs about 1 kg; the full box 11 kg. The set's contents are: Negative images 1) R 4891 P1N2 Virgo cluster of galaxies 2) J 3721 P1N3 South celestial pole 3) POSS-II Field 460 SF06346; RA 19h 33m; Decl. +30º; Milky Way with SN remnant 4) POSS-II Field 278 SF04014; RA17h 16m; Decl. +45º; Globular cluster, airplane trail 5) POSS-II Field 143 SF04069; RA 20h 6m; Decl. +60º; Galaxies, Open cluster Positive images 6) J 2155 Field 97; RA 13h 56m; decl. -65º ; MIlky Way showing dust clouds and clusters 7) R 3409 P1 Field 334 Milky Way with massed stars and dust clouds 8) J 331 E1 RA 00h 54n; Decl. -73.00º; SMC (Small Magellanic Cloud) 9) J10231 P2 Field 718 Stars and galaxies 10) R 5275 P1 Field 141; RA 19h 00m; Decl. -60º; Many stars and prominent globular cluster" | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1975-1985 | Source: | University of Aberdeen | Creator: | ROE, Edinburgh | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
