For the "zoom", use the <Tab> key to go between the two possible zooms. The "zoom" in FotRSU was meticulously set by CapnScurvy after quite a bit of testing and adjusting and testing some more. You field of view and the zoom are as close to "real" as the game allows. That particular mission starts the player too close to the ship and does not give you sufficient time to do more than maybe two attempts at ranging and speed calculation. You do want to find the ship's course, and then get as close as you can to minimize any inherent errors. The stadimeter is only as accurate as your screen display, and as steady as your hand is... I usually just get within 1000 yards on the 90 and shoot at the 12-20 degree angle, depending upon the target's speed (Fast 90). Also, the SH4 owner's manual actually doesn't do too bad with the functionality of manual targeting (SilentHunter4 Manual.pdf)
