This will provide you with your binocular's full field of view from horizon to zenith simply by adjusting the mirror angle. You will not have to tilt the instrument itself in any way. It is much easier to detect motion when the image is stable. We were simply astounded by the short period of time it took observers to detect a satellite whizzing by. I'm a beginner.
Many objects are simply better in binoculars.
Comets and open star clusters show their full glory in low powers and wide fields. Cheap telescopes can be hard for beginners to set up and use. Many beginners make the mistake of buying telescopes that offer high power with little light gathering aperture. This results in poor image quality, dim image brightness, and a very narrow field of view. Seasoned astronomers will tell you to learn the sky with binoculars and then look for a good telescope.
