The region of M8, M20 and M21 with celestial interloper Saturn photobombing the shot. This is one of the first photos I took using the camera's Astrotracer feature, which tracks the stars internally. The camera was mounted directly on a tripod: no external tracker was needed. This was just a test; more subexposures would be needed for a truly decent image. No reduction of chromatic aberration in software has been done and the image could use it (the vintage lens I used contains no ED elements). No flats, darks or bias frames were used but I did use LENR and I dithered between shots. The full APS-C frame has been cropped somewhat for better framing.
