Description

Sh2-119  H2 region.   Also known as the Clamshell nebula is a large emission complex in Cygnus, surrounding the bright star 68 A Cyg. Several dark dust lanes and globules cross the nebula creating suggestive dark filaments.  (Wikipedea)

This nebula is near the North America Nebula.  Good Ha signal but very low O3.  Tried HOO but the image was primarily red.  Took Ha O3 and Blue with the intent of adding some higher frequency blue to do a Ha(O3+B)(O3+B).   It also was very red.  Did not take the time to get RGB data to do a Ha-RGB but may do so at another time.
