JPARSEC Sky Atlas and calendar events for 2019

JPARSEC Sky Atlas and calendar events for 2019 Tomás Alonso Albi Observatorio Astronómico Nacional, Madrid (Spain) @ Instituto Geográfico Nacional C/General Ibáñez de Íbero, 3, 28003, Madrid (España) http://www.ign.es

This simple sky atlas is focused on amateur astronomers that don t need a basic atlas neither a too much detailed one. It is designed to be printed in long side duplex mode and A4 size, and handled in landscape orientation. The first part shows the sky for each month, including a detailed list of the astronomical events for each month. Limiting magnitudes are 6.5 for stars and deep sky objects. The second section shows the sky atlas itself, with stars up to magnitude 8.25 and deep sky objects brighter than magnitude 11 (some fainter ones will appear if they are in Messier or Caldwell lists). For each chart there is a table showing the deep sky objects visibles on it, sorted by magnitude. Additional tables show the main double stars (from https://www.stelledoppie.it, primary/secondary brighter than magnitude 7/8.5 and with a minimum separation of 10 ) and variable stars on that chart. Coordinates for the atlas are astrometric, referred to the Julian epoch of the atlas year. Some events or objects could not appear in the tables when there are too much entries. The total number of stars in the atlas is around 60000, with 1100 deep sky objects (850 in the tables), 450 double stars and 75 variable stars. The total number of astronomical events is around 1100. This atlas is free and has been developed by Tomás Alonso, using the JPARSEC astronomical package (http://conga.oan.es/%7ealonso/doku.php?id=jparsec), which is distributed as free software under GPL license.
