These are detailed renders of planets in varying sizes for use in space combat games.  

They have a hex-grid overlay matching the hex grid pattern used in the paper maps for Squadron Strike, and are compatible with Squadron Strike, Squadron Strike: Traveller and Romance of the Seven Realms.  The hex grids show the difference in altitude above and below the plane of the map.

They're laid out on 12x18 sheets, and you will probably want to print them on cardstock at FedEx Office or Staples on cover stock.
