With the Moon well past the cluster, this is the easier night — the one to actually count.
NASA describes the Pleiades as a slightly fuzzy grouping of six to seven stars to the unaided eye, with binoculars revealing far more. So count twice: first with the naked eye, then through glass.
The difference between those two counts is your own light-pollution report. It tells you more about your sky than any map, because it is measured from where you stand.
Write the numbers down. Next month, same cluster, you will have something to compare.
For the binocular basics, see the Starter Kit.
