Preparing a night session using PhotoIRmote as intervalometer.
You can see how we configured the app. We took 20 photos of 35 seconds of exposure each. We set 5 seconds between each photo (enough time because we don't use the noise reduction camera option).
Note that shooting stars have been added using photoshop. The photoirmote setup is the needed one to get still stars in open sky at night. If shooting stars are bright enough they will be captured though :) We weren't so lucky :(
Hope you try it and have fun!
