Another attempt at doing star trails. This time I took fewer and longer frames - each frame was at least 10-15 minutes. Then I put them together using lighter color for a layer blending mode and came up with this. There's a bit of a gap because I reviewed the first frame before pushing the shutter for the second frame. The rest of the frames I didn't pause, started the exposure immediately after finishing the one before. I used a wireless remote this time to trigger the shutter. Worked much better.
