This image shows you several dimmed nebulae distributed in northern region of Cepheus's pentagon.
A reflection nebula in lower has an ID of vdB152, you can see a thin stripe of dark nebula has been stretched in north direction from the nebula.
And at north of 24 Cep, a dark nebula of LDN1235 is lying. The shape of nebula gives a nickname of "Shark Nebula".
You can detect more minor objects in this image like a planetary nebula of PK111+11.1, a part of arc-shaped emission nebula of LBN538, and so on.

This image has taken the northern part of Cepheus with span of 17×11° centered on vdB152 and LDN1235 (Shark Nebula).
A bright star at the lower right-hand side is β Cep.
Maybe this image looks like covered in haze, actually this field has been covered with an extraordinary huge and dimmed molecular cloud floating at the northern side of Milky Way in autumn.
Besides the Shark Nebula in center, LBN558 at 2.5° northeast and so on are dense regions of the molecular cloud by chance.
