The weather was fine all day up until i started capturing. Then the clouds came. Of course right in front of the sun!!

Images with 1.5x barlow:


Took a break because of the clouds. Then shot these as it cleared up a bit.


Captured right after.


I noticed how quickly these loops were developing so i started on time lapse B.



Time lapse:

Sequence A - 600 frames were captured every 30 seconds. Sadly i had to stop only after 15 minutes due to clouds.

Sequence B - 600 frames were captured every 30 seconds. Again i had to stop because the clouds got thicker.

These are the clouds that appeared as i shot Sequence A. I took a time lapse of those clouds.
Captured an image every 5 seconds, 749 frams in total. It took the computer 20 hours and 12 minutes to convert and process the RAW files.

I noticed something peculiar as one of the planes flew past the cloulds. As if it was draging heavy turbulence with it. But does turbulence really move that fast at that altitude? Think it's more of a coincidence.

Here is a 100 frames zoomed in version.
