A few Q's from a newbie

[nesrall]

I have a few questions,maybe someone can help me out. Stellar- when you create a warp point opening into an anothers(ally or enemy) system..can they see the new warp point?...system wide nebulas-Is there planets to be found hidden in the systems that contain system wide nebulas? Crystaline torps- I had assumed because it was a "torp"...that PDG's couldn't target them...can they or can't they?..Crystal armour...does crystal armour regenerate X amount of points to the shields when the ship is hit...or when the armour is hit? & Lastly...Medium storms that say opaque to most scanners...any idea what level scans they prevent...or if you have a ship in there is it as visible as if it was cruising right thru the system? Thank You for any feedback on the above Q's.
