TWEEDLEDEE AND TWEEDLEDUM IC 4756 (top) and NGC 6633 make for a pretty pair of open clusters. The field of view for IC 4756 is 100′ while for NGC 6633 it's 60′. Foreground stars pepper both images, making it somewhat tough to identify cluster members. sk yand tele scope .o r g * AUGUST 2022 25 JIM THOMMES (2)http://www.skyandtelescope.com
