LBN 321 et al., Kn24, Kn25

Another less imaged region in constellation Cygnus.

Several faint nebulae from Lynds Catalog of Bright Nebulae: LBN 321 and LBN 316 on the right – LBN 284, LBN 290, LBN 296, LBN 299 and LBN 304 on the left side.

The exposures without filter are only used for representing realistic star colors. The nebulosity in this images is simply too faint to produce a nice image.

The bright star in the lower center is 61 Cygni, while the bright star in the right is 65 or τ Cygni.

More interesting are the two planetary nebulae Kn24 in the top right (sweep once) and Kn25 (sweep twice.). Especially the latter one popped out as a pretty bright patch. I did not know about this nebulae and it took me a while to find out where to search best for these objects. I found them in the HASH PN database, a collaboration of the University of Hong Kong, the Astronomical Observatory of Australia and the Astronomical Observatory of Strasbourg.
