In the rich area of the contellation of Cygnus we can see Sh2-112, Sh2-115 and PK85+04.1. Sh2-112 and Sh2-115 are both diffue nebulae with a strong HII emission. The first is supposed to lie at 5700 ly from us and the second at 7500 ly. PK85+04.1, aka Abell 71, was supposed to be a planetary nebula unless it was correctly identified as a HII emission nebula too.
