Best Jupiter Yet 8/26/2011

It seems the baffling made a substantial difference.  The wee hours of 8/26 had very clear skies, but steadiness wasnt very good.  Nevertheless, I got probably the best Jupiter pictures to date.  I have photographed during better conditions, but the images I got on this evening are far superior, and I can only imagine what I'll get with better seeing conditions.

As you can see, the oval BA is resolved.  I can also make out some color in the center, and a grayish border is also there.  The color isnt perfect, because I also noticed an increase color fringe due to the fast 2 element objective.  Where I only had blue color fringe, I now have some red starting to appear as well, and it is becoming more difficult to eliminate it.  This is why the planet has a greenish hue.

If you can ignore the hue, you will see 2 additional, separate northern belts are resolved and appear somewhat busy.  The Equatorial zone is showing more detail now.  I'm not sure whats up with the southern belt where the BA is located, usually these belts are somewhat straight, but in this image it is very crooked.

Overall, I am quite pleased considering the seeing appeared to be about 3/10.  The planet was expanding and contracting wildly as I was taking the AVI's.

Here is a monochrome image taken from a different AVI, which was shot in monochrome.  The amount of detail, especially in the equatorial zone is even greater, with some additional detail in the north polar region.  Notice the white spots near the north pole.  Again the Oval BA is well resolved in the southern region.

This is one of the first images taken during this session.  Again, a lot of detail.  There appears to be a bit more detail here in the equatorial zone in this color image than in the first image, however although the Oval BA is resolved, it is not as sharp in this image.

The only real difference between these images and previous images is the addition of that one baffle in the optical tube.  It was suggested that a couple more would be optimal for this scope, and that might very well be true, but with the addition of only 1, it sure seemed to make quite an improvement.
