Although it appears about 25′ wide on the sky, its real span is roughly 3.1 light-years — the difference is a measure of how far away it lies.
Observing Caldwell 68
Caldwell 68 lies in the constellation Corona Australis and is best placed in the evening sky around July. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the southern hemisphere, and sits low for those far north. Note that the listed magnitude is spread across the whole object — diffuse galaxies and nebulae are often harder to see than the number alone suggests, so dark, moonless skies help a great deal.
