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.
