Top 500 binary stars


Recommended Posts

I put this list together because I wanted a list of binary targets in a format that I could sort, filter and comment upon.

The data file is in a spreadsheet for ease of sorting and modifying in Excel, Google Sheets, Libre Office etc.

The fields include object name(s), location information and star data – magnitudes, separation and position angle. Also included is a rating (5 being the best) which helps me prioritise targets, observed colours and a description. Finally, there are columns to add your own rating (I use T for targets here), date of observation and comments.

There is a note sheet and a separate sheet is used to produce a CSV export file for the SkEye app.

Original data sources are the Coldfield Observatory list of 200 most beautiful double stars and the Saguaro Astronomy Club Double Star Database.
