The Star Almanac for Land Surveyors Her Majesty’s Almanac Office NP321 - 2017 electronic edition About e-SA Bookmarks Page Finder Stars by Constellations THE STAR ALMANAC — ELECTRONIC EDITION ABOUT the e-SA 2017 This electronic edition of The Star Almanac for Land Surveyors (e-SA) is the paper edition in electronic form which is produced by H.M.Nautical Almanac Office part of the UK Hydrographic Office. The e-SA is the SA with bookmarks and extra “pages” that provide links that allows easy navigation to all the tables, examples and sections of the explanation. The pages are most usefully viewed as facing pages so both left-hand and right-hand pages are visible at the same time. If the option ‘Return to the previous page viewed’ is readily available, then this will make returning to the previous page e.g. the Book mark pages that lists all the sections and tables or the Page Finder, which gives links to all the tabular material, easy. The list of stars by constellations with Bayer letter and star number gives links for navigating to the correct left-hand page that lists the right ascensions. This star finder is listed over two pages. There are also navigation boxes to these initial pages at the bottom of each page. Pages may also be navigated to from the bookmark-sidebar.
