Too many consecutive galaxies for me. Still in Centaurus but for a magnificent globular cluster this time. The largest and brightest.

A huge galaxy group for you to have a go at this May. A varied mix of bright(ish) galaxies to impossible amongst its 1500 members. A challenge from Owen for 16" and up under dark, transparent skies.

A potential quadruple system (for a spectroscope) in Boötes that's accessible for small scopes. But a stiff challenge for 25-cm of aperture in Lupus from Bob this May.
