I can't find new zones. The observatories produce scanned results but I can't figure out how to use them. (doing this in creative mode) How do you use that?

I would like to say I am also having this problem. With other mods and with just base game, the observatories create scan result objects that have the appearance of telescopes and seem to not be able to be used. This happens whether I am in cheat_mode=true (free crafting) or not.
The portals themselves with the belts and chests work on Nauvis and are a great feature so thanks for that.

Fixed in 0.5.4
