NGC 6840: Visible at 48x as a small clump of stars. 97x: Ten
stars within 5'. Oblong NE-SW. Most stars in two subgroups,
brightest mag. 11.5. Might be a real cluster. 

Orig. descr. W. Herschel (1784): "A S. forming Cl. of st."
J. Herschel (1833): "A small poorcluster; the preceeding of two
distinct clusters. The stars 11m."
NGC 6843: Suspected at 48x as a eF grainy glow. 97x: Smaller and
more difficult then -40. Size 5'. Brightest stars (mag. 12) N
and S. Quite difficult in this weather but exists. 

Orig. descr W. Herschel (1784): "A Cl. of co. sc. L st. not
J. Herschel (1833): "A small, poor cluster. The following of
