Sky & Telescope - May 2024 - 63

Now look less than ½° south to see a much smaller and
fainter flying-geese outline (also circled) and also pointing
west to east at the proper-motion line. This is the small and
faint version and is best seen through larger scopes. However,
most star atlases only show the large and bright pattern, so
depending on your field of view and size of telescope, it's possible
to assume these two asterisms are one and the same.

At the Oregon Star Party (OSP) in July 2023 while searching
for Barnard's Star with my 80-mm scope, I confused the
larger flying-geese asterism with the smaller one, which was
too subtle to be easily seen at low power (13×). My quest thus
became a confusing back-and-forth effort comparing my eyepiece
view with charts that almost matched the view but not
quite - it was exasperating. I knew the problem had to be me,

CENTURIES OF MOTION Use this finder chart to zoom in on Barnard's Star. The first thing to notice is that the path shows 204 years of movement,
starting in 1916 - the year E. E. Barnard discovered the star's huge proper motion. Its 10.4″ of yearly motion will have added up to nearly 0.6° during
that time - greater than the apparent diameter of the Moon! Also note the vastly different scales of the two flying-geese asterisms. Making sure you
identify both - especially if you're using a relatively small telescope - is an important step toward pinpointing the current location of Barnard's Star.
