NGC7790 is a medium sized open cluster positioned about 2.5 degrees northwest from beta Cas, the western star of W-shaped Cassiopeia.
You can see it a bit lower part in this picture.
And there is another open cluster of NGC7788 just 16-arc minutes northwest from NGC7790.
These two clusters have an impression like very compact double-clusters.
NGC7790 and NGC7788 have apparent diameters of 17 and 9 arc minutes respectively, both have several tens fine stars gathered in sparse.
Though you can detect this pair only with compact binoculars, not so striking because they're bathed in the Milky Way.
