In fact an easy way to find the cluster for those using binoculars or telescopes without setting circles
or GOTO is to sweep down from epsilon and delta Cas (the left hand side of the W shape of Cassiopeia) and continue for just under half the distance between these two stars.
For the majority of observers therefore setting circles
or a Go To telescope will be necessary to find it.
Most people these days locate it using go-to systems or setting circles
, but for star-hoppers wanting a challenge the best starting point is probably mag 3.
