This open cluster is located in a star field that's free from bright stars. Its most remarkable figure reminds me of a reaping-hook, and is composed by four stars between magnitudes 9 and 10. These are also considered the brightest members of the cluster, besides these only a couple of stars of 8-10m are visible in the field of vision, but most of the members are fainter than 12m. For about 20' to the south is the planetary nebula PNG138.0+04.1, but its nebulosity can only be suspected even by using averted vision - the large, 5.5' diameter planetary cannot really be seen even with the UHC filter on. However, its 13m central star can be found and a little haziness can be detected next to this star that is probably illuminated by the brighter stars next to the central one.

Awesome sketches! I love it! I was curious what size and what kind of eyepiece were you using with each sketch? I do see the magnification power with each sketch. Thanks - let me know, email address
