Although it appears about 0.7′ wide on the sky, its real span is roughly 3.7 light-years — the difference is a measure of how far away it lies.
Observing Caldwell 109
Caldwell 109 lies in the constellation Chamaeleon and is best placed in the evening sky around February. Its maximum altitude above the horizon depends on your latitude. It sits far enough south to be circumpolar from mid-southern latitudes, and never rises for most of the northern hemisphere. It is faint — plan for a moderate telescope and a dark, moonless sky. 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.
