4 years, one frame each summer 2007 through 2010. It moves a tad over
10" of arc per year, about 41" during the time of this animation.

If the skies ever allow it, I'll add a fifth frame but weather here has
been zilch for imaging for weeks now. Not looking promising either.
Humidity running higher than a rain forest screws up transparency this
low in my skies from 47 north.

I wouldn't have guessed that. Cool. Over how much time did you compile
those images? In other words, how long did it take the star to move that
distance in the sky?

Is it okay if I cheat and read the filename? ;^)

Proper motion of Barnard's Star - very cool!

And thanks for all the great images you post.
