My prime interest was in the SEB. The wake was fluttering with details that I could never get the whole of but I made out the most general structuring. At 173x to 200x the three pips of or white spots following the GRS would materialize often then vanish, never completely b ut morph into a confused area. I really gave patience here and observed cat like for those better moments. Normally the 240x plossl is tops for Jupiter as all seems to pop nicest with a nice clean edge. In the case of the tangle of detail here the complexity of contrasts and ever the fluttering britling details it became obvious that I flat out needed to see it closer without the jumble. With that I jumped up to 260x and that was better, even then onto 303x and that was fine too. I was pleasantly takwn aback by the fact that the jovian limb wasnt showing typical amibiguety of focus as the seeing here in CT will often not permit such things. Well what the heck, so in goes my 5mm Abbe Orthoscopic and 364x and let me tell you THAT was the ticket. The hat trick of fluttering details layed down about as good as it was going to get. The white spots were chambered between these dark projections that each had a secific width, waist and tapering shape complete with transitory gradient value. The old conventional wisdom of 200-240x being max and soft ever after took a holiday tonight. These were features mere seconds of arc wide and the same way magnifications one might use on a 4" Mars were clearly paying dividends here. Im not sure if its because of the features or the orthoscopics versus barlowed plossls to get the same magnification but while my old high end assumption for Jupiter was 275x on a 9/10 night that was clearly redefined tonight in 7/10 seeing. The WHOLE of Jupiter was best at 200x to 240x but the details just seconds wide, or in the case of the sub arc second BA the other night, made the use of these high power oculars not just a nice thing to have but necessary. I am sooooo glad I got these Abbes.
For all that theres still features and intensities in the SEB that were persistent but too too flighty to mark with certainty with a pencil. I just COULDNT reliably call it and to that affect I have some regret in conveying the SEB as I have as it was alive and fluttering with details - I just COULDNT map all of them.
The rest was less work than the SEB safari, but they were fun nonetheless and challenging too. That GRS II of the North shown as a soft grey intrusion into an other wise clean area. Too the NEB had these darker intensities and one in particular that was at an angle and sausage like. I couldnt nail the white spots in the south but this little guy was there in all its murky glory. The festoons had classic sweeps. In ther past 9/10 seeing has shown the whipped swirls BETWEEN the festoons which is a rare eyefull, but tonight it was merely the festoons un to thyemselves and the gentle contrast gradients bordering the belts. At the base of the festoons some white spots or areas in the EZ were the whitest things on the planet. subtly but clear. The NTB was unusual I saw some dips and such in it an dits northern edge was sharper than its southern and most interestingly WIDENED at the following end. The last thing observed was this little thin light toned zone with some darker belting contrasting it. This was a subtle feature but rewarding in that eye candy way those threshold features flicker with curiousity.
I didnt have any Europa transit this time nor sub arc second spot off the GRS as it rotated off before I got set up. Still this was a busy observation.
A side note I tried for Ganymede detail at the wonderful 364x and then 450x again, abbes and all for naught. All it highlighted was that 7/10 isnt 9/10 and the 450x orb was too smeared to settle down. It takes an unusually small target like this and unusually high magnification to reveal the wall of seeing that exists between these two seeing values. They look close but either youve got 9 or youve got 7 seeing and wishfull thinking doesnt fix it. But I kn ow Ill never quit wishing till that seeing comes around again.
Hope you like.
