Around the southern region of Perseus, this compact open cluster can be found about 4 degrees west of California Nebula (NGC1499). The cluster is sandwiched in two major scenic spots in the winter skies of California Nebula (in east) and the Pleiades (in north). But NGC1342 is a very commonplace object with a diameter of 14 arc minutes and a magnitude of 6.7; it can hardly be paid attention.
Although this photo shows the cluster is fairly sparse because that was taken with a focal length of 1200mm, you will be able to appreciate a pretty group of stars with binoculars. And the cluster has been surrounded with dimmed molecular cloud, you can show it in this image.
