β Aquarii

Beta Aquarii is Sadalsuud ("Luckiest of the Lucky"), just southwest of alpha and easily found with the naked eye.

With beta on the bottom edge of your glasses, you'll have M2 on the northern edge: binoculars.

M2 is a rich globular cluster of about 100,000 stars. With an apparent visual magnitude of 6.4 under perfect conditions it's accessible to the naked eye (with averted vision). The larger the instrument the better; medium sized telescopes show a bright nucleus and some star chains as well.


With beta centred in your glasses move two binocular fields west to 12 Aqr.

12 Aqr (Struve 2745) is a lovely binary with colour contrast, yellow and blue: 5.8, 7.5; 196, 2.3".
