Imaged Jupiter last night at around midnight and after processing this morning noticed a large black spot in the southern polar region
Any ideas what it might be ? A huge storm maybe ??

Hi Martin
That black spot would have been the shadow transit of Ganymede which started at 21:41 to 23:55 EST.
The seeing was average early in the evening but improved after midnight for a few hours before turning for the worse a few hours before dawn.
Thanks Guys
Thought I had discovered a new phenomenon on Jupiter , wishful thinking
As Ganymede is only small you wouldn’t think it’s shadow would be so huge on the planets surface considering the shadow is cast through the vacuum of space.The shadow size must be accentuated by our own atmospheric dispersion or similar
Cheers

Your spot on
I took 4 off 1500 frame videos about 5 mins apart, this one was the best of them
Planet was jumping around to much
If I waited another hour when it was up near the zenith then things might have been a tad better , too tired so packed it in for the night around midnight
It’s a learning curve this planetary imaging but I think I’m getting somewhere with it
Thanks Bob
I took a single image of Jupiter nearly 2 years ago up near the zenith in winter and it was really sharp, without any processing.This little newt is a winner !
I don’t use photoshop for AP
Registax 6 for lunar and planets
Startools for DSO,s
I have often said not to underestimate the ability of a six inch Newtonian telescope...
You back me up in spades.
Nice image. Great capture well done.

Thanks so much and yes you have always said the 6” newt is a great scope !!
I always manage to snag a good image either DSO, planetary or lunar from the 6”
Cheers
