Quote:
If that one's too tough, the somewhat wider pair of 8 Lacertae (22") would be a good next target.
Or these, all seen in 10x50s.
the fairly even double theta Serpens, 63 Ser, theta, Alya, 4.5-5.0/22", easily resolved,
61Oph, 6.0-6.5/21” easy to see difference in magnitude
24 Com, 5.2-6.7/20.3”, 12h40m +18d30m, south of Berenices Hair
12 CVn, alpha CVn, Cor Coroli, 2.9-5.5/19.4”, wide difference but still fairly easy
Stf 485, Cam 7.0-7.1/18”, 4h05m +61n, easy, in o.c. 1502
and for a real challenge
Stf 2690 Del 7.0-7.2/16.7", 20h35m +11.5n, even mag 7 double, clearly separated in 12x50, but much more difficult with 10x50s due too fainter magnitude.
Close doubles are fun in small binoculars.
