M67 (NGC2682) is an open cluster about 9 degrees south-east of the Praesepe (M44), with a diameter of 15 arc minutes.
The cluster is positioned just 2 degrees west of alpha Canicri, so it should be easy to find the figure like a nebula with binoculars.
You can appreciate the individual stars with a telescope over 6cm (2.4"), plenty of faint stars with magnitude about 11 to 13 are scattered like gold dust,
and detectable that the whole of shape is like a hemisphere.
