Hydrogen Clouds Near Deneb


By  Ron Brecher
( astrodoc.ca )

This field is northwest of the bright star Deneb, which is just outside the right edge, near the top of the image.
This means it is close to the North America Nebula, and is part of the web of nebulae that seem to be everywhere in this part of Cygnus.

Most of the objects in this field lie at a distance of about 5,500 to 7,500 light years.
To provide a sense of scale, Sh2-112 is about 25 light years across.

Moravian G3-16200 EC camera (on loan from O’Telescope), Optolong Ha, R, G and B filters,
