So i presume that is manual focus like most of their others. How are you finding it is to dial that in for nightscapes and what not without auto focus and setting it to infinity?

most, if not all lenses don't work in AF for shooting dark sky images, and many in my experience require some fiddling and experimenting to get proper focus, most do not get critical focus at infinity. I have rented two different Sigma 20Art lenses, and both of them were a bit different for what was critical. My Batis 18 is pretty easy with the OLED, you can see it at night and after using the SharpStar to help, I know what point is perfect focus for stars.

I use the Rokinon 14mm f/2.8, also manual focus. I dial in focus on a distant object in the daylight, then use some electrical tape on the lens to hold the focus ring in place.

That’s never worked for me. I always bump it where the electrical tape didn’t hold. I usually just live view the moon or some brighter star in 5x mode and then switch to MF and recheck every so often.

I zoom in with live view to a bright star and set focus manually then try not to touch the focus ring from that point on

Sounds like you are looking the Sharp Star. I heard they are more for longer lenses rather than wider ones. It is basically a bhatinov mask commonly used on telescopes, which are longer focal length. Is it worth getting?

I do have the SharpStar and find it works great for wide angle too...

I like the composition for sure. I also wonder about how many images were used etc.

On another note, your profile mentions you are from Central CA, where about?

I live in Salinas and always looking to get out with some local people to shoot. Couple friends and I get out occasionally and I am trying to plan a night shot in late Sep. Perhaps you might want to join?

This was actually taken just east of Pinnacles National Park...then I drove home throughSalinas. I live in Visalia but I am always out & about in Central Cali. We could for sure plan a meet up. Just PM me.

This was two shots.....the foreground I took a little earlier in the evening while the moonlight was available. The sky was later at night & I had to darken it a bit to bring out the MW. Rarely do I do a composite so this was fun for me.
