Jupiter 16 March (Double Shadow Transit)

[MarkS]

Taken around 10:50pm on Sun 16 March.
IS DBK 21 on Celestron C11 with 2x Barlow
500 frames at 1/30sec stacked in AutoStakkert and post processed in Registax
The shadows are of Io and Ganymede.




Here's one from earlier in the evening just after Ganymede had passed in front and before its shadow was cast on Jupiter:

Guiding was much better than Saturday.  I was getting 0.4arcsec RMS for long periods on my belt drive EQ6.  It occasionally went above 0.5 RMS.  The type of the seeing conditions helped.  It was the high speed "jittery" kind of seeing instead of the "slow wave".  Guiding works much better with the former.

Very nice indeed Mark - looks spot on to me. You did well... John

[Carole]

I've managed to tease just a bit more detail out of the Jupiter/Ganymede image by using 2500 frames instead of 500.  Here they are side by side:

Certainly a lot more detail Mark, was definitely worth doing.  Looks like a bit of detail showing on Ganymede.
