IMPROVED this mornings JUPITER - Feb 26

Hi All, had another go at the avis from this morning, picked one of the better ones and ran it through Virtual Dub to reduce the number of badly distorted frames. Very time consuming and perhaps not the most rigorous job, but it does seem to reduce the amount of onion ringing (not eliminated)and improve the overall sharpness of image detail.

I've put three different approaches in the attached image ... let me know if you have a preference, though the different approaches have turned out remarkably similar images. These would now be my best with the C9.25, but not quite up to the standard of my run with the Mewlon 180 on Feb 18.

cheers,

great stuff,

middle one wins but not in all categories.

it wins with the less obvious onion rings and festoons

1 & 3 seem to have more detail around the mini GRS.

i had forgotten about this mini GRS, this is a great sot of it mate - well done!

It's a hard task to pick just one of the three as a favorite that's for sure, their very similar as you said.

Hmmmmm...I'm picking the middle one because at first glance, to me the onions are less evident (unless your making a point of looking for them) & it looks slightly sharper than the other two.

All three are great images though, Good stuff Rob!

Great job there Robert.
There's not much in it between the last two if you ask me, but I'd agree the middle one takes out the prize money.

Well done Robert - a great result from some quite difficult atmospheric seeing conditions.

Cheers

Thanks for pointing that out DP, I hadn't realised what it was, now on closer examination I can see it's obviously a storm system similar to, but only 1/4 size of the GRS. Jupiter is an amazing place

Chris Go calls it a "Red Oval BA", and saying Jupiter now has 2 GRS's Well, one Great one.. maybe one mediocre one

Looking back through my images, I caught it on the 21st January to the RHS of the image here.

don't know about "mediocre red spot", I prefer the "not as Great as Great Red Spot, Spot" or NAGAGRSS for short
