You can add a weblink to your message to make the heading an active link direct to your website.

All rented stars display a small, coloured, flashing symbol to make them more prominent on the star map.

To create your star message:


  • Go to the star maps and choose a constellation by clicking on the down arrow below the constellation name.
  • Click on any star that is not flashing and is within the constellation's red boundary.
  • Click on 'Make this star yours, with a message here', then follow instructions.
