Bright, a bit more than one field northeast of Deneb, large, coarse, resolved, a conspicuous cluster of 6-8th magnitude stars roughly triangluar in shape and 30' in diameter

Large! Bright!! loose and sparse open cluster of a few dozen stars, members stars are quite obvious as they are much brighter than the general galactic background, about ½° in diameter, distribution of the member stars seems fairly random in nature

A surprise! a large (30') and loose cluster of bright stars across the field.

On October 27, 1774, I found in a triangle west and east with the two stars Pi at the tail of Cygnus a small star cluster, the position of which relative to the given stars I determined with the heliometer, as shown in the 6th figure.

Cluster of stars near the tail of the Swan; one can see them with an ordinary telescope of 3.5 feet.
