M13 - Globular Cluster in Hercules

Discovered by Halley in 1714, M13 (NGC 6205) is one of the most
prominent and best known globulars in the northern hemisphere. At a
distance of 25,100 light years it is 145 light years across.

Hey, moron, you ever tried actually looking at these? They're
impressive sights even in small finderscopes some of them, and even
easier to find, although as you're incapable of doing anything
yourself you can find them with most goto mounts or hooking up
computer based planetaria packages to your telescope.

In fact most Galactic globular clusters are quite crap in either
photographs or electronic images in comparison to their visual
delight.

M13 is especially rewarding as switching between averted and direct
vision at low powers reveal two quite different seeming objects.

Always one of the easiest beginner ones, along with not too very
distant M57, when teaching beginners the earliest rudiments of
starhopping.

Starhopping is probably illegal nowadays though, in favour of helping
fools with too much money pointing rentascopes and pretending they
know something in order to think they look good and are clever.

Why not contribute something positive for a change.
