No, you're not. You're not understanding how the image was made. It's a mosaic made between sunset and sunrise, as the sky was moving. It is possible with such an image to capture all of the ecliptic except about 20° on either side of the Sun, which will be too bright. Compare the image with any decent star map and you'll see that it covers a bit under 300° of starry sky.
Think of it this way: if you want to observe some particular object along the ecliptic, you only have about a 50% chance of catching it at any given time. But if you wait all night, you can observe almost anywhere along it. (That's not just true for the ecliptic, of course. If you've ever done a Messier marathon, you know that the timing is critical- you start with objects low in the west after sunset and end with objects low in the east near sunrise.)
Oh, yeah, OK. You're really right. I do apologize.
I forgot the rotation of the earth. So even if you fix your camera on tripod, you can take almost 180° panorama from sky, at night, without rotating your camera.
And this amazing picture is an almost 350-360° panorama (except the sun itself). Yes, it's true.
I'm so ashamed.
But I want to be a great astronomer. Can I?
If you want to be an astronomer, you have to consider what it takes to become one. I briefly considered becoming an astronomer myself, but then I realized I would have to work with equations all day (or a lot of the time anyway), and I knew that I couldn't do it. I became an astronomy nerd instead, getting my knowledge from reading and looking at pictures (and asking questions of other people, for example here at Starship Asterisk* - a great learning experience).
Ask yourself if you've got what it takes to become a professional astronomer. If you believe that you do, then go for it! Go to university, and work hard to get the money to do so.
But you should ask someone else, preferably Chris Peterson who is himself an astronomer, how you should go about to become an astronomer yourself.
And remember that even if you end up doing something else than astronomy for a living, astronomy is always there for you, for example here at Starship Asterisk*!
