40 frames at 180 seconds each, Canon 5D Mark III ISO 3200, Samyang 135mm at f/2.0. No guiding or dithering. Kuraiskaya Steppe, Altai Mountains.

Thank you. Were the stars removed, or are they not there? Also, I wanted to ask about the Samyang at f/2 (star uniformity across the field and vignetting)?

Here, about a quarter of Cepheus is in the frame. I did remove the stars, of course, using the PixInsight Starnet. I really like the Samyang lens, even at its widest aperture. At f/2.0, I'd give it a 4 out of 5 for corner sharpness on a full-frame sensor; starting from f/2.8, it's a solid 5.
