A small open cluster of NGC7235 is positioned about 1 degree south of zeta Cep, a southeast star of Cepheus's pentagon. The star has been captured in upper part of this picture. NGC7235 has a visual size of 4 arc minutes, you can recognize the cluster like a dimmed lump of faint stars through small sized telescopes.
And you can see another minor open cluster of NGC7261 in upper left hand side of the picture. It has an impression of fairly sparse and compact cluster. The cluster has a size of about 6 arc minutes, a bit larger than NGC7235, but you can find out NGC7235 easier Than NGC7261 because NGC7235 has denser stellar density.
