Europa puts a beauty mark on the Great Red Spot

I was cruising facebook some weeks back and found one of those “On this Day” which had me wondering what happened.

So I went and checked my annual gallery for 2013-2014 and found it wasn’t finished and posted!😨

So, without ado, here’s my 6 year old post made of 3x derotated images with a composite single image of the shadow and moon.

3 GREAT nights on Jupiter Nov 7-9, 2011

We finally got a break and some nice seeing from November 7th to the 9th.  I got a shot of Uranus on the 2nd night which I'll post later.

As always click to get full size and here is the rest of this season!

Night one's 2 shots:

and the seeing deteriorated later

2nd and BEST night!

Moons with reference:

and monochrome channels:

I knew the progress of the High Pressure moving overhead meant peak on the 2nd night, but the forecast for the 3rd was good.  I knew it couldn't be as good as the 2nd night and I only stayed out for 1.5hrs on the 3rd night.  Managed one nice shot:

Jupiter in avg seeing

I'm finally gaining some rhythm with the new scope and weather.  

I hope to be ready for lost sleep and some good seeing.  SOMEDAY!

Jupiter Oct 23/24

BE SURE TO CLICK EACH PHOTO FOR HIGH-RES views!!!

Two nights of decent to above average seeing and a nice double transit weekend before last.

1st night had better seeing:  Oct 23, 2010

Great Red Spot

Oct 24, Dual moon events:

Left to Right -- Ganymede, Io, Europa (under Ganymede's shadow) and Europa's shadow just on the right edge...

By 0224UTC Io has disappeared behind Jupiter, but seeing improved such that Europa is clearly defined and it's shadow has moved further towards the center

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.
