Amazing. I sure neverever did such an amazing image.
A question: how long was the exposure? 120 sec as I read on your oppening lines or 5 hours+ as someone suggested?

There was a 120 second exposure around dusk to get the details on the tree and the ground, followed by 672 x 40 second exposures to capture the stars. Therre was about one hour between thr dusk shot and the start of the star shots, so the total time of the shoot was about 8.5 hours.
I use CS6 a lot but have never attempted image stacking. What is the process?
From bridge select your photos, tools>photoshop>open as photoshop layers, once the images have loaded select the top layer and shift-click the bottom layer to select all, set blend mode to lighten, flatten, save.
I work in groups of 80 images (d800e 14bit RAW) using 32gb of RAM. Try to keep the total size of your images below 50% of your available RAM to avoid using the scratch disk.
For an image like this I repeated the stacking process about 10 times then at the end I stacked the 10 flattened images together.
I tried a star trail last year but my lens quickly fogged up. How did you avoid moisture condensing on you lens? Or do you live in a really dry location?

During summer i dont have any fogging issues, during winter i use a kendrick astro dew heater. You can also use chemical hand warmer sachets available from camping stores, they emit heat for 3 or 4 hours when exposed to air.
! What a crazy shot! Way to think out of the box!
