To simplify this, I am only interested in hearing from actual users of this lens for Milky Way photography. I have other lenses (Sigma Art which I love) but they are very heavy to cart around and I was looking for a lighter alternative. I’m using the Nikon 20mm 1.8 on a Nikon D 850. How far do you have to stop it down to eliminate coma? Last night I shot it at 2.4 and the coma was severe. I find it hard to see coma in the field on the LCD screen even when enlarged and dark skies are about 2 plus hours away so field experimentation is difficult, hence my inquiry. Any experience based suggestions would be greatly appreciated. Thanks.

I always set the lens wide open when shooting Astro, and on a D850, I've found that 10 sec @ ISO 1600 or 5 sec @ ISO2000 works best.

But, please post an image with haloing so we can see.

Thanks for the assistance on downloading an image, this one should be better, jpeg, 1080 on long edge and original stored. Straight out of camera and horizon will be corrected etc etc, am mainly looking for coma opinions on the Nikon 20mm, thanks again to all for helping out on this, I have not posted an image here before and appreciate the guidance.
