I call it the 600 rule (some use 500.)

600 / focal length = exposure time.

For instance, using, say, a 20mm lens. 600 / 20 = 30 seconds. Anything longer will start to produce trails. Also, you must take into account the crop factor of your camera. I use a Canon 7D which has a 1.6 crop factor--so the equation is: 600 / (20 X 1.6) = 18 seconds.
Very cool, I didn't know any of that. Thanks for getting back to me, I'll give this a shot the next time I'm out.

Pete.....That is an awesome pic. The plane is so nicely lit up by the moon. Assume you used a fairly wide open F-stop and/or a high ASA for the stars and so you could keep the exposure short to avoid getting star tracks. Nicely done.

I shot a star track shot of the Tetons circa 1985, 6 hour exposure, has to be a moonless night, of course.

Just read through the entire thread...absolutely GORGEOUS pictures! Thank you to all who have shared. Elk Hunter, that beard is epic manliness. Thumbs up. Those of you who live out of town...is it pretty common or recommended to have brush/grille guards on your trucks and SUVs?

Thanks, MRVphotog---this was 16mm, 12 seconds @ f2.8, ISO 1250.

I'd say it's fairly common. All I can say is that a month ago I sure wish I'd had one on my truck. A nice, buck deer decided to test his fortitude with my front end. We both lost. He lived, although he had a heck of a limp (I wish we could legally put them out of their misery,) and I got a $6000 bill for repairs.

Use this when it's cold because it's got a heater. That's my cabin in the back ground. Also, note the trailer over on the right.



Here's what that trailer looks like now.
That is beautiful work on the trailer/buggy, EH.
