Symbol Set 3 gives you and assortment of modern rather than SF symbols. Cosmographer Pro does contain the sci-fi symbols and was primarily designed for use with Campaign Cartographer 2. If you are using Campaign Cartographer 3 there is a compatibility upgrade you will need to download to use these symbols. A Cosmographer 3 is I believe under development which will be very worthwhile based on the upgraded png symbols in other -3 products.
If you don't have Campaign Cartographer 2 or 3 you will need to get them as neither Cosmographer Pro or Symbol Set 3 are stand alone products.
