Sh2-134 Widefield
Sh2-134 & 135
Located between the popular „Wizard Nebula“ and „Elephant's Trunk Nebula“, this area is often overlooked and rarely photographed, though it has to offer a lot of faint, but spectacular objects like the emission nebulae Sh2-134 and Sh2-135, the open star cluster NGC 7261 and a bunch of LDNs and LBNs.
In order to bring out as many details as possible, I decided to use the false color technique, that got famous by the pictures of the Hubble Space Telescopes. The "real" colors are assigned to other colors: sulfur (Sii) = red, hydrogen (h) = green, oxygen (o) = blue. This results in an increase in contrast, and more details become visible.
