Teutsch 26, Open Star Cluster
Teutsch 26 is listed in SIMBAD as an open star cluster. But there is no further information except the coordinates and the apparent diameter of 2.7x2.7 arcmin.

In my 20" f/3.2 telescope "Teutsch 26" appears very faint and roundish at a magnification of 270x. The cluster is located west of two brighter stars (at about 13mag)
at the edge of a dark nebula (LDN 604), which is also quite visible. The background appears grainy and about 5-10 very faint individual stars flash out with indirect
vision. Of these, two are slightly brighter than the rest. The cluster has a very low surface brightness and requires a dark sky and a lot of aperture. All in all a great
sight. :)
