Time lapse Europa transit

This is an 11 frame sequence where each frame, of red only, consists of 10sec or 400 - 500 frame stack.  Each frame is taken back to back so, 11 frames x 10sec per frame = 110seconds or just shy of 2 minutes of rotation time.  Each of the 10 motion frames are displayed for 100ms or 0.1sec, the last one is held for 1second.  This means that 10frames x 0.1sec = 1second of time per 'spin'

So, long story short, in 1second you'll see nearly 2 minutes of Jupiter's rotation, that's over 100 times normal speed.

What's really interesting is how far the moon and shadow move in only 2 minutes.  This is taken with my Celestron C8, 2.5x PowerMate and PGR Flea3.  EFL ~  5080mm or f/25.  The stacking and processing was done at 2x up-scaled and the final rendering in Gimp gets rescaled back to 1.5x or 150% sized.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
