NGC7129 is a reflection nebula in Cepheus which contains Herbig Haro (HH) objects. These are formed when high speed narrow jets of partial ionized gas ejected by proto-stars collide with nearby gas and dust. The LRGB image below represents about 10 hours integration time and was taken with my Esprit 150.
The location of the HH objects are identified in the annotated version of this image, which can also be found in this album.
