M16 is a very bright emission and reflection nebula with an associated star cluster. It contains the famous „pillars of creation“, made popular by an iconic picture imaged by the Hubble-Space-Telescope. These are star forming regions, clouds made of dust and gas, illuminated and sculpted by the strong radiation of young and bright stars.

M16 is quite low in Presberg. As a test of the new ASI 2600MM Pro I imaged the nebula on the 6"-Newton.
To avoid the wall covering the telescope aperture I had only a small window of opportunity during the culmination of the nebula.
Following the modified bicolor technique by Cannistra and Wechselberger by combining starless Hα- and OIII-frames for a synthetic green channel a pseudo-RGB-colour version was created. Then RGB-stars were added.
The starless version shows the structures in the inner part of the nebula quite well.

Again seeing was terrible while transparency was amazing.
