This is how the sky looked for the majority of my captures. It cleared up completly later on.


Lots of thin clouds but i was determined to capture the sun. 62GB in 175 AVIs later became these images and animations.

All images and time lapses was captured in double stack mode.

The following mosaic was captured through thin clouds. There was a small eruption in progress so i had turned down the exposure so it wouldn't burn out completely.

Time lapse:

Sequence A: 600 frames were recorded every 30 seconds.
Captured through thin clouds. I've tried to adjust most frames to reduce the amount of flickering. There are 3 frames that burns outs. The clouds cleared up in those 3 shots.
