Fantastic photo, Ron! Isn’t the White Rim trail something else? One of my fav places in the southwest.

I agree! Good suggestion.

Can you say REI!

Thanks Paul,

Good eye – yea that was a plane that flew through the scene right at the beginning of the exposure.

Very nice. I like how the tent shape mimics the peak. Just a graphically very strong image. There is also a bit of a diagonal line running through the stars – plane?

Great composition. reminds me of ET’s heart light!

Hi Mark,

Well this is a different kind of noise then what we usually associate with digital photography. With long exposures, you get these bright pixels. My understanding is that the dark frame needs to not only be the same length of time as your exposure, but under the same conditions (temperature, humidity etc.). So I can’t wait until I’m back in Alaska to do my 25 minute exposure, or the bright dots won’t appear in the same the quantity or intensity.

Then I need to refresh my memory on the next step. Somehow you invert the image and combine it so that the now black dots block out the bright ones – I haven’t read up on this part for some time – a good winter project as long as I don’t delete the black frame in editing – something I already almost did!

Ron, ok, this may be a stupid question – but isn’t a 25 minute exposure with the lens cap on the same as a 1/100 sec exposure with the lens cap on? I have heard of the black frame subtraction before, but guess I don’t understand the technodetail and mechanics of it.

Thanks guys!

I haven’t done these before, and you are right, I didn’t have much time for experimentation – that is why it was only 25 minutes, I couldn’t wait any longer to see if it was working!

My first attempt was close, it was just too bright out. I lit the tent from the backside for about 20 seconds. There wasn’t a moon, I could have done a multi hour exposure – next time. I also did a couple of 25 minute exposures with the lens cap on just in case I need to do a black frame subtraction to remove noise. Need to read up on how to do that, but at least I have the frame.

Sweet shot Ron. Similar question to Richard – I was wondering how long you had to light with the flashlight. With a 25 minute exposure, I wouldn’t think there were a lot of “re-dos”.

Great idea Ron. Did you do a lot of experimenting with the exposures or had done this before?

Thanks a lot everyone!

Bret – a motorcycle would be a nice way to go on that road, and most roads around here!

I have tried Star Trails on a number of occasions and failed every time. I am thinking of giving them a try on Wednesday night when there is a meteor shower as well. Nothing like this to provide a little inspiration. Great work as always Ron. I look forward to more from the trip.

I came to your blog tonight to ask if you planned to do any star trails in Moab–and there it is! Nice shot.

I’m planning to do a White Rim trip on my motorcycle next year. This gives me even more incentive, Ron. I’m glad you guys had a great time and I can’t wait to see some more images!
