Okay, for the moment, forget about time dilation.
Are the following descriptions accurate if you do not account for time dilation?
I've been going over and over this in my head and I can't figure out why any of these don't make sense.
Setting: A ship going .99c.
1
Attached to the rear of the ship there is a pole pointing parallel to the direction in which the ship is cruising. The pole is 5 light seconds long. Looking out a rear-facing window which is directly next to where the pole is fastened you see the pole like looking up a tall building from it's base. Even after correcting for the illusion of inflated height caused by standing so close to the base, the pole appears to be 500 light seconds long, not 5 light seconds long.
2
There is another pole 10 meters long attached perpendicular to the direction of the ship, to the side of the ship. You are able to view this pole from a side-facing window, 10 meters behind where the pole is mounted to the hull. Looking out at it the pole appears to be shorter than it actually is. Also, looking at the portion closest to the hull it looks normal, but as you look at the pole further away from the hull, it appears to be warped so that you see it as if you were looking along at an angle much smaller than the one you are.
3
Looking at the same pole as mention in 2, you are able to view it from another view port 10 meters away from it. This time the view port is closer to the front of the ship than where the pole is mounted. Looking back at the pole it appears to be much further away and much much smaller than it actually is and the angle at which you see it does not appear correct. It looks like the pole is much further away than 10 meters.
4
There is yet another pole 5 light seconds in length attached to the hull of the ship. This pole is faceted to the front of the ship, parallel to the direction in which the ship is traveling. Similar to the rear-facing pole, there is a view port right next to the base of this pole. Peering out this port gives you a few of the pole from it's base, but the pole appears much closer than it is and is distorted so that each part of the pole appears to be about half the distance of what it is. It still appears to be 5 light seconds in length, but looking at the tip, the tip it looks as if you are only about 2.5 light seconds from it.
5
You observe a planet from the ship which is 10 light minutes away and almost directly in front of the ship, the ship will miss it by only a few hundred kilometers. You look upon the planet and judge it to be 10 light minutes away. A minute later you look again, and it appears to be about 9 light minutes away. Another minute passes and it looks about 8 light minutes away.
