This is how the Swan appears through a moderate to large aperture scope. See the shape of its body, horizontal on the water, and the graceful bowed neck? When you view the Swan through a telescope, try bumping up the power a bit and concentrate on the circular area inside his neck. That little bit of space is devoid of all but the faintest stars; it looks like a black hole! If the sky conditions are good, you will really notice the 3D effect this gives to the Swan.
