Most telescopes come with a small, straight-through finder telescope. But many astronomers prefer the use of larger, right-angle finders that offer many more advantages. With a 50mm finder, you can hunt down fainter objects that you would not see in smaller 24mm or 30mm stock finders. "Correct Image" finders present a view that matches the orientation of the sky or the orientation of the stars in star charts. And, perhaps most importantly, your back and neck will thank you for using a "Right-Angle" finder and no longer subjecting them to various contortions at the telescope.
