ESASky target lists
The ESASky target list feature accepts .txt file format. To add text or comments to your target list (which will be displayed in the target list menu below the player buttons), put the following in your text file:
<TARGET OR COORDINATES>@desc@<DESCRIPTION>
M31 @desc@The Andromeda Galaxy, M31, is a spiral galaxy approximately 2.5 million light-years away.
M33 @desc@The Triangulum Galaxy, M33, is a spiral galaxy approximately 3 million light-years away.
M51 @desc@The Whirlpool Galaxy...
The feature accepts also coordinates in the RA/DEC or l/b format, with all the options described in the help for the search field feature. The application will use the equatorial (J2000 RA/DEC) or the galactic coordinate (l/b) frame to interepret the numeric values in the target lists, regardless whether the coordinates are given with two floats or in hexadecimal format.
This short movie shows the target list feature in action.
