This fine globular cluster shines with a magnitude of 5.1, making it one of the five brightest and largest globulars at all. The reason is that M22 is only 10,400 l-y away. M22 would be more famous if it did not have such a low declination. M22 appears fairly large in my 15x70. The granular core is non stellar and shows a somewhat triangular or fan shape. Its N and E edge are more distinctly visible against the fainter halo. A few pinpricks show up near the edge of the fading halo. But these might be foreground stars.

As you have written this would be an even more magnificent sight if it were more overhead. Nevertheless a most impressive wide field binocular drawing. This was the first object in Sagittarius I saw through a "large"( 4.25") reflecting telescope many, many years ago. I saw it about the way you have drawn it here but not with the wonderful wide field of view. Great work Rony, I can only hope you have many more to go.
