The constellation of Sagittarius holds quite a few interesting Deep Space objects. One of them is the Trifid Nebula (M20, NGC6514), another star-forming region. Besides the main emission nebula, there is a blue-ish reflection nebula (showing only dim in this narrowband image) and a dark nebula that causes the fractured appearance.
For this image I tried a different approach: hooking up my D-SLR 24-70mm f/2.8 lens to the astro camera. My sensor is small, but it still yields a nice wide view with the lens set at about 35mm focal length. You can see one of the most exiting parts of the Milky Way in the constellation of Cygnus: North America and Pelican Nebulae, The Sadr Region with the Butterfly and Crescent Nebulae as well as the Cygnus Loop (Eastern Veil, Witches Broom, Pickering’s Triangle). See the next image for an annotated version of this. Again, this is a narrowband image based on 1hr and 50 minutes of data in Ha, Sri and Oiii channels. Processing has been done with PixInsight ("Forax" color palette) and Photoshop.
The open star cluster NGC6823 in the center of this image is surrounded by an area of nebulosity NGC6820. It includes a reclection nebula and a fainter emission nebula (SH2-86). Location: Constellation of Vulpecula. Distance: ~6000 lightyears. The object is not very bright and it took me 3 (short) summer nights to record it with my narrowband technique.
