This is 215 images at 10 seconds each - roughly 35 minutes elapsed. I had to stop because the exposure what out of range - I could no longer take 10 seconds exposures. The exposure was shot auto and then corrected in post which wasn't easy. There is some motion in the tripod - I think got warmer or I touched it a bit. I corrected the motion in post. I have blended the images to make this a 45fps video and to try and remove some of the residual brightness flickering.
