NGC 457 is an open cluster located in Cassiopeia, often called the Owl cluster, or a more recently the E.T. cluster with the two brightest stars forming eyes. I tend to see it more as an Owl. The cluster contains some 150 members and has an estimated age of around 21 million years. Less than idea weather for imaging, with a thin cirrus clouds, but a good bright target for commissioning the RC 10 scope and the ZWO 2600 mono camera.

Messier 35, and NGC 2158, two open clusters located in Gemini the Twins. These are more like distant relatives. M 35 is relatively near by at only 2,800 light years, and NGC 2158 is a distant 15,000 light years away. M 35 is a young cluster at around 150 million years old, and NGC 2158 is an old 2 billion years old cluster. M 35 has an abundance of bright blueish stars that burn through their fuel at a faster rate, and only the older more yellowish survive in NGC 2158.
