 how can I use Orbit HUD in space to line up all the markers to the target?
You don't. You user the warp HUD for that.
I can't do any better than this.
But what about this that you said- I was trying to figure it out because it seems like this would work ("another option"):
It's because you are not pointing in the same direction you are travelling. Follow the velocity vector.

Another option — drop out of warp and use the Orbit HUD mode.

well now I'm onto a new target, so I'll see if I can do that with this (NGC 300.....the nearest spiral outside of the Local Group, about 6.7 MLy away.)
I have a question though, I'm not going to use hyperjump because I can't get it lined up with the target.  Is it okay if I just use boost exponent and not use rotate to target or use hyperjump at all?  It moves the ship in weird directions and never at the target and I hate having to destroy ships and start over.  I just use the bottom left control panel and center the target with that just like you can do in Planetarium mode and then build the ship and turn on the engines and boost exponent and away I go!  Simple and elegant right?
Here is the start of my current journey.

As you can see from the above neither hyperjump nor rotate to target are turned on, I find they do weird random things by moving the ship in unexpected directions even after I have my target selected and centered like above.  So I will do it this way which is much more intuitive.

The autopilot will set up a trajectory towards your target. It may have to boost at an angle somewhat perpendicular to your path to the target, in order to "bend" your flight path towards the target. If you don't want to let the autopilot finish each phase of its hyperspace jump routine, there's not much more I can tell you.  There is a step-by-step of a flight in the flight lessons, is there not? You have to do your homework.

And I've mentioned it before — you like the keep your main engines on when in hyperspace. Nothing wrong with that, I suppose, as you can accelerate to very high velocities, both real and effective. But you never take into account the deceleration portion of your flight. You will blow right past your target when you get there.

But you never take into account the deceleration portion of your flight. You will blow right past your target when you get there.
The problem is if the flight isn't straight and direct what happens is what you mentioned before, it zooms me right past the target on a completely different trajectory.  I like the straight line course since it's the fastest way of getting there as opposed to moving away from the target which makes it extra long.  So this is a completely different thing from the velocity vector not lining up with the target?
I think maybe I should do it your way for added realism as opposed to the convenience I want lol, but the thing is it doesn't initially blow me past the target because the ship automatically slows down before I get there.
So in summary, do you think I would have gotten to my target, it would just have taken a little more time, using hyperjump, even though the target wasn't lined up (and said it was unstable when I put the target in the center of the frame)?  So this wasn't similar to the velocity vector not lined up on target issue?
And what's the difference between using hyperjump vs manually adjusting boost exponent, isn't it doing the same thing just in a different way?

Yes, the boost exponent is the hyperdrive. But you are just pushing buttons without understanding how the SE hyperdrive works.

When the hyperdrive autopilot first starts up, it aligns the velocity vector with your target. It may boost you in a direction not to your liking, but you are talking about a few hundred kilometres at best, compared to 6 million light years? How far out of your way is that?

Plus you are picking very distant targets which would normally takes the typical SE ship days, weeks, or even months to get there. You can crank up the real space velocity to get there quicker, sure — even use black holes as a slingshot — but then you also have to slow down at the other end. If you are under thrust all the way to your target, half of that should be decelerating.

Pick a closer target. Watch the SE autopilot do its thing.  The velocity vector is the direction you are travelling in space. You have to do engine burns to bend your path towards your target. I don't know how simpler I can put that.

I would like to add that before you answer to Mr. Abner with more questions, you should go back to the basics with baby steps. His advice here is really valuable, as you keep going through the same problems because you are not taking the time to understand how the Flight Simulator really works, first using the manual that was sent multiples times, then by experimenting with easier scenarios.

You will never figure out how things work if you go for the big fish right away, so go easy for now, follow the manual (here it is again: http://spaceengine.org/manual/space-flight-school/ ) and you can come back here asking specific questions once you have mastered the basics. Good luck!

The problem is I gave it 24 hours to correct the course and it didn't.  I posted the screenshots, the velocity vector and the target never aligned.  So I figured a more hands on approach by making everything line up was the way to go.
It's like taking a picture in manual mode vs auto mode.  In manual mode the user has more control over all the functions.
If the program slows down my engines as I approach the target do I still need to do engine burns and deceleration though?  Is there a way for me to do engine burns manually (just by changing the speeds on the engines I take it?) or do I need to use the autopilot hyperdrive for that?  The images I posted from near the center of M31 and M33 showed that the drive automatically slows me down and then shuts off before I pass the target.
Also, I wanted to share this, most of the markers are lined up, except the purple warp vector.  Is this still on target to get to NGC300 in a few hours?

Thanks, I decided to print it out since it is actually easier to read that way.

First of all, keep in mind that by default, the SE hyperdrive autopilot does not use the main engines. Except for setting up the warp vector in the first place, and sometimes some mid-course correction.  And you are still picking some extremely distant targets, and wanting to get there in a few minutes.

The blue Warp delta-v is the vector you point to in order to put your purple "Boost vector"  on to your red target.
990-00328.jpg
Here the ship is burning main engines to put the warp vector on to the target. The delta-v is shown to be 3.64 km/sec. You would see the purple warp vector moving towards the target as the delta-v counted down to zero. Then the main engines turn off, the ship points towards the warp vector (which now should be on the target), and the hyperdrive kicks in.
990-00329.jpg
We are now doing a sedate 0.11 light-year/second (that's the way I like it). 

In your last pic, the delta-v is very small, less than 1m/sec. (When the velocities are very near zero, the vectors will disappear from the screen.) But then you are still 2.4 million lightyears from the target. That tiny angle of offset between the warp vector and the target will grow as you approach the target. And at such high velocities (4,468.68 km/sec) it may take a very long burn to get you back on track if you wait too long.

I actually have no idea if I made it to my destination (I was within 3 hours), because I fell asleep and the computer automatically shuts off in the middle of the night.  It probably made it there but I noticed there were no warp effects going there, which means I probably wasn't using the warp properly.  So I read more from the manual and decided to try it your way.  First let me completely outline my method so it's easier to figure out what I might be doing wrong.
1. Start Space Engine
2. Use Find Object from Left Control Panel to Find Earth and Go There
3. Use Find Object to Find NGC 300 and Select Ok
4. Use Lower Left Control Panel to Center NGC 300 on my screen.
5. Use Spacecraft Manager from Left Control Panel to Build New Spaceship.
6. Take Control of New Spaceship.
7. Switch New Spaceship to Warp Mode.
8. Go back to Find Object in Left Control Panel to Select NGC 300 again.
9. Use Lower Left Control Panel to Center NGC 300 on my screen again.
10. Set Main Engines to 100 to start movement.
11. Set Boost Exponent as high as it will manually go (11.637).
At this point I had my first error (field unstable, turn to target, etc., even though the target was centered on my screen.)
12. Rotate to Target.
13. Hyperjump.
I definitely have the warp effects back and I love the look, however, I'm not sure I'm headed in the right direction even though I had NGC 300 completely centered when I built the new space ship.  Not sure where I went wrong or what else I could've done because this happened 4 times in a row now.  But I'm hoping that you're right and it's just going to take the scenic route to get there.
Here's a screenshot with some nice warp visuals.

No no, not a few minutes.  I am shooting for 17 hours for this target (for some reason my computer does some weird things and starts shutting things down if I keep it on for 20 hours, so I have it set to automatically shut off after just under 18 hours to stay on the safe side.)  So 17 hours is a hard limit for the time I let it stay on.  I outlined my entire method from memory in the post above so you could hopefully know where I went wrong.  This time I used the method you suggested and got the nice warp effects back :) but  I'm not sure if I still did it right, I think I'm missing something.
As mentioned in my previous post it said I was within 3 hours of my target but I fell asleep (during an incoming hurricane with lots of water rescues going on last night!) but this was the last screen shot I have before I fell asleep from that previous mission.  It didn't have the really nice warp effects so I'm pretty sure I didn't do that mission right.
This screenshot is from 12:30 am last night so I wasn't asleep yet but this is the last screenshot I took from the previous mission.  I was awake until around 2 am and the mission had about 2 hours to go until completion and when I woke up at around 8 am this morning my computer was off so I don't know if I got there (I probably did but without warp effects it wasn't worth it to me- I guess simply using Boost exponent isn't enough, I really need to use Hyperjump to get the nice star effects that happen when in warp mode.)

Fellow Alex, I wish there was  a way to magnify the area around the target to see if everything is locked in or not (or maybe a color change to show that everything is correctly oriented and a flashing message that all systems are GO?) Because I used the automated method and it still seems to be misaligned but I'll keep it on this trajectory and see what happens.  I have 17 hours to go lol.
