Here is my first test image with the Astrotech ED60, covering the wide field around the Antares Nebula Cloud, nearby globular clusters, and bright nebulas.

This was taken with a Nikon D5300, unmodified, so no cooling. Shot at ISO 1600, 70 x 40s unguided subs. It is a test image, and I know the ASI1600MM-C will be much smoother.
