![]() The previous versions of the SAC double star database were created by starting with a large professional set of data, usually the Washington Double Star (WDS) catalog. We are not foolish enough to believe that it is complete, but it should be a good starting point for many amateur double star observers with modest telescopes. Many members of our astronomy club have always enjoyed the beauty of multiple stars and in an effort to provide a list of these objects, this project was started. Saguaro Astronomy Club Saguaro Astronomy Club Double Star Database version 4.0Ĭlick here to download the database zip file. See the NOTE at the bottom of the Revision History, we will keep an updated errata file at the SAC web site from now on and allow users to update their version 8.1 files as needed. Thank you to the skill, knowledge and expertise of all who helped the Saguaro Astronomy Club create this listing of what to observe in the deep sky. Crayon, David Fredericksen, Jack Jones, Jay LeBlanc, Matt Lutinnen, Peter Argenziano, Paul Lind and Paul Dickson. Stephen Michael Schimpf spent much time with the NOTES field, finding errors and trying to make the data more consistent.īesides myself, I am going to list the dedicated group of people who have helped keep this an up to date and useful database: Bill Anderson, A.J. Brian Skiff of Lowell Observatory has been a constant help with a variety of information about deep sky objects. Their work is reflected in this release of the SAC database.Ī small fraction of the number of objects still persist as NONEXISTENT, compared to the beginnings of this database. SAC wishes to thank all the people who have spent many hours searching for, and correcting, errors in the NGC. You can search and sort the data with a text editor. SAC_DeepSky_81_FENCE.TXT is version 8.1 of the SAC data as a text file that has vertical bars between the fields.Any modern database manager or spreadsheet will import the data in this format. This is also called CSV for comma separated variable. SAC_DeepSky_81_QCQ.TXT is version 8.1 of the Saguaro Astronomy Club database in quote, comma, quote delimited form.It contains information on over 10,000 deepsky objects. There are lots of possible ways to search and sort the data in this popular spreadsheet. SAC_DeepSky_81.XLS is version 8.1 of the SAC data as an Excel spreadsheet.These are useful files, but they did not fit the information style of the main database. POTPOURRI.TXT is a set of information about a wide variety of astronomical phenomena from white dwarf stars, red stars, meteor showers, common names and more.REVHIST.TXT is the revision history, a short file about the various releases of the SAC database.Please spend some time reading this info before trying to utilize the database, it will help you to use this data effectively. There is information here on the data fields and what the data means. SACDOC.TXT is the documentation for the SAC database.This ZIP file contains the following 7 files: As always, if you find an error, please let us know. How far we have come from the list of the brightest 300 objects contained within Burnham’s Celestial Handbook, all typed in on my Apple II+. Thinking it would be an easy task, here we are more than 25 years later, still maintaining and updating a much larger listing of information about what to observe at the telescope. This club project started many years ago, when we wanted a listing of the brightest deep sky objects on our computers with 64KB of memory on floppy disks.
