I like the big , fat star trails -- looks like the jump to light speed

Paul, thank you! That's came into my mind, too, when I saw the result

I'm actually a fan of star trails that splay out like this. The hint of rotation around the Polaris and Sigma Actantis is pretty cool.
Mark, thanks!
Glad you find it cool

Nice shot. the foreground is quite nice. The star trails seem a little thick with gaps. For a noisy night shot you may not notice being slightly out of focus with your foreground as much as you'll notice with stars.
I recall a very similar shot recently but behind some low bushes with more light glow on the right. Was that yours?
I think Jim meant -
Many current lenses, particularly zooms but also some primes, do not have a hard infinity stop. I guess more lenses had this back in Jim's younger days - lol. Anyway, that means if you just move the focus ring to infinity, you will not have the sharpest stars possible You need to go to live view, magnify, find a bright star, focus until sharp as possible. Then tape it down. I had a manual focus wide angle pancake lens that did have hard infinity stop, but the coma was horrific.
I don't, but should, do star trails. My unqualified comment would be those gaps in the trails could be easily corrected by certain options in stacking software. You may want to explore that.
Again, nice shot especially since this was an experiment!
Okay, show me your Milky Way images!

David, thank you for deciphering Jim's comment for me
I did exactly what you describe, focusing in LV mode, except it was not the bright star but rather a bright object about mile away, but for this lens it should not matter.
The "approximate focal distance" in EXIF is 4294967295, so that qualifies as "infinity", I guess.
Yes, you remember it well, I posted a picture from the same area a week ago, that was from my scouting trip. Milky Way picture(s) will be coming tomorrow.

Cool!
I'm a little surprised the sky is tolerably dark so close to Phoenix.
There are several programs that will 'add' a bunch of shots together to make smooth star trails. You might play with http://www.startrails.de/html/software.html http://www.markus-enzweiler.de/StarStaX/StarStaX.html etc.
p.s. I like the divergent stars!
Greg, thanks! I did stacking in PS, but will try the ones you mention.
This location is very cool because it is close - just 40 min drive from my house, has dark enough sky to observe Milky Way, and also provides some ambient light on a butte.
Sasha.
