A sample star is shown, and the Explanation tab explains the columns. If you want to convert lists of stars from equatorial to galactic co-ordinates and galactic XYZ, you can use the bulk_converter Excel 2007 spreadsheet – just copy/paste the RA/Dec or alpha/delta (decimal coordinates) and copy the formulae in the tables. (Thanks to Veeger, PraedSt, and Grant Hutchison from BAUTforum, and Spaceman Spiff and Selden from the Celestia forums for all their help with figuring out the conversions).ĭownload: Coordinate_converter: J2000.0 equatorial co-ordinates galactic co-ordinates conversion spreadsheet

The spreadsheet requires the Right Ascension and Declination (in hr/min/sec and deg/min/sec respectively, both in J2000.00 epoch) and the J2000.00 trigonometric parallax values (in arcseconds). All of these data can be accessed from Vizier and other sources. The Excel 2007 coordinate_converter spreadsheet allows you to convert between J2000.0 Right Ascension/Declination and Galactic Latitude/Longitude (both ways) for a single star, and also provides X/Y/Z co-ordinates for the star if its parallax is known. stars added to datasets that had been omitted for various reasons). Section 5 lists any updates to the data presented on this page. Section 4 presents links to additional articles that expand on the Stellar Mapping page! Section 3 provides some advice and ideas for combining and presenting the data in Astrosynthesis. AstroDB files are not included here since they can be easily generated using Astrosynthesis after importing this data. The data is presented in CSV (comma separated variable) format, which can be read into both Excel and Astrosynthesis. Several star datasets and catalogues are provided (each with its own advantages and disadvantages) that include stars up to 300 lightyears from Sol. An Excel file is also provided for users to convert from RA/DEC to Galactic Coordinates and back again.

Section 1 describes the techniques used to convert existing astronomical data into a more usable form. The stellar data is visualised using Astrosynthesis 3.0, published by NBOS, which is available for $35 from DrivethruRPG and RPGNow (I strongly recommend buying it if you’re interested in this sort of thing – which presumably you are, since you’re reading this – it’s an excellent 3D visualisation tool!) Every effort has been made to make the data as simple to interpret as possible, though FTL routes have not been calculated here. This dataset is aimed at anyone interested in astronomy or who is interested in adding nearby stars to their own RPG or sci-fi/Traveller universes – the raw data is easily adaptable to any sci-fi setting or RPG. The aim of this project is to show the locations of the stars around Sol as accurately as possible.
