IC 5070 is an emission nebula located about 2,000 light years away in the constellation Cygnus. You can find two more images of this nebula in this web site. A wide field one, that also includes NGC 7000, the North America Nebula, and a higher resolution HaLRGB image, taken with the 32 inch Schulman Telescope.

This image is a 3-pane mosaic that has been taken with narrowband filters (Halpha, OIII and SII) and mapped to its natural colors. This region shows an intense OIII emission line and this helps to let lots details to stand out. Many scientifically interesting objects (Herbig Haro Objects and Molecular Hydrogen Clouds) are shown in the region corresponding to the “neck” of the pelican (lower right) and a detailed in an annotated copy of this region can be found below (based on the image taken with the 32 inch Schulman Telescope, mentioned before). In this annotated image, up to eleven such objects are shown. Some of them have only HH numbers, other only MHO numbers and some have both numbers, as they appear in both catalogues.
