50 Deep Sky Objects for 50mm Binoculars
The objects in this chapter are visible with medium-sized binoculars, although some are visible in much smaller instruments.Most of the objects to the far south, for example, are easily visible in 8×30 binoculars. With the exception of objects that fill the eyepiece in 10×50 binoculars, all of these objects are better viewed, in the sense that more detail can be seen, in larger instruments. Similarly, many objects in the list for 100-mm binoculars are visible—or at least detectable—in smaller instruments, but often no detail is visible. For example, under good conditions an experienced observer can see the Ring Nebula, M57, in 10×50 binoculars, but it is stellar in appearance.
