Stellor Manipulation (Gives Solor sails, Solor Panels, and Hyper Optics)
Stellor Harnasing (Monoliths however they are bloody expensive. They are best for long term economy though)

It should be: Stellar Manipulation (gives Monoliths and a lot of various stuff including Planet Creators, Warp Openers, Warp Closers, Ringworlds and Star Destroyers) and Stellar Harnessing (Gives Solar Sails, Solar Panels).

- The trick of using recon satellites require Stealth Armour and any kind of sensors (Hyper Optics is the cheapest of all), not the Scattering Armour (which counters Long Range Scanners).

In short, the basic strategy in SEIV can be sumed up in a single word: expand! Then you will have the leisure to toy with ship designs and other parts of the game.
