Penmon Point Star Trail final by Photosbykev Penmon Point Star Trail final by Photosbykev
2016 images taken over 6 hours and about 6 hours of post editing to remove all the aircraft trails.

Updated to remove a minor flaw I found in the processing

16-09-10: Thank you for the DD and the support :)

How it was made:
Canon 5D MkII and Canon 24mm f1.4 MkII lens shooting 10 second exposures at f2.8 @ iso 1600 continuously for 6 hours. The final result was 2016 images captured on a 64Gb CF card. I also shot 20 dark frames with the lens cap on to use for noise reduction.

The camera was powered by an external 12v battery which also powered the dew control heating tape wrapped around the lens to prevent the lens misting up ( but the heater died after an hour so I had to regularly check for any condensation on the lens )

The raw files were converted to 16-bit tiffs in Capture One Pro.

The tiffs were then individually checked to remove any aircraft trails, about another 6 hours work lol.

Startrails.exe was then used to compile the 2016 images and 20 dark frames to produce a single tiff file.

The composite image was then finished in CS5 ready for printing and display.

The computer used runs Windows 7 64-bit on an i7 system with 2 x 200Gb solid state drives for temporary working space, 24Gb of 1600Ghz ram and 4 x 2Tb drives for local storage.

Hey mate, amazing photo!

I'm curious, and sorry if this has been asked already but google has failed me, but how does ones power their slr externally? --> 'The camera was powered by an external 12v battery'
...My star trails fail becasue my battery life isn't long enough...

For the Canons you can make or buy a dummy battery pack with a voltage regulator inside that you use instead of a standard battery.

This is an amazing photo, I've been trying to do similar photos but none have turned out nearly as good as that!

How long did you wait between each photo?
Did you use a computer program to take the photos or do you have something you plug into your camera to do it?

Thank you for this inspiring pic. And also for the detail on what it took to make it possible. The possibilities for of multiple exposure are wide-open. What are the lines that you left in? And is that dawn coming on?

The two long lines are satellite trails and the smaller streaks are iridium flares. The glow on the horizon is light pollution. The arcing lines along the right hand bottom corner are the navigation lights from a fishing trawler.

This technique of yours, using dark frames to reduce noise, how does that work? Do you have a link to a tutorial or something that explains the technique?

it's a well known and trusted method of increasing the Signal to Noise ratio when shooting astro photographs. There are a number of tutorials that describe the process, this thread is a good place to start [link]

Thanks! You see, I got my first DSLR last August, so I still have a lot to learn about digital photography, especially stuff that isn't covered in the manual.

An absolutely beautiful shot, and a true example of persistence paying off. My only question is where did you get that computer, and what kind of processor. I mean, damn... That is one beast of a machine.
