Not many other details were seen, some festoons, parts of equatorial belt, and the GRS was bordered on its preceeding side with white rim.

Lately, Oval BA is prominent and relatively easy to see given halfway decent conditions. Keep up the good work.

Well done. It was a first for me, too. I dunno, I like the contrast you pulled out of Jupiter given the conditions, especially the two toned NEB. That's not easy.

That's not easy. It was not easy but it was there (the equatorial side was visibly darker). Few days earlier, in better conditions, I could even see in the same telescope some white long spots in NEB: Post Extras:       Asbytec Guy in a furry hat Reged: 08/08/07 Loc: La Union, PI Re: Jupiter 9.11.2012 - first time seeing oval BA [Re: Sasa]       #5513986 - 11/11/12 04:32 AM Edit   Reply   Quote Quick Reply   Quote: It was not easy but it was there (the equatorial side was visibly darker). Few days earlier, in better conditions, I could even see in the same telescope some white long spots in NEB. Yep! You got it! Again, great observation, Sasa! I think that bright spot in the left sketch has been dubbed "the beacon" by some imagers. I think that's it. Did you post your previous sketches?

Congratulations on observing Oval BA. Your sketch on the 6th of Nov. depicts the region of Jupiter I observed last night. Lots of detail in the NEB and EQZ in your sketches. Thanks for posting.

Oval BA, to me, is elusive to view, and here he is, with a great sketch of it.

It seems to be getting a bit easier to pick out, or maybe I've just had pretty decent seeing lately. I saw it clearly in the 18-inch two nights ago (ok, maybe that much aperture is cheating, but wow, there were some very interesting details in both the main belts, and the equatorial band was very wide within the EZ, but I digress...), and again last night I caught it in the 10-inch, just rotating into view on the eastern limb. Thanks again for posting your fine sketches. -george Post Extras:       Sasa sage Reged: 11/03/10 Loc: Ricany, Czech Republic Re: Jupiter 9.11.2012 - first time seeing oval BA [Re: george golitzin]       #5519609 - 11/14/12 02:32 PM Edit   Reply   Quote Quick Reply   Thanks George, I saw your sketch in the other thread. It is very nice and full of details. Definitely bigger aperture counts here. I still have two bigger scopes than 100mm ED: AS110 and ED130. Haven't seen Jupiter through them this season yet. Sill not in the same league as 18" mirror, but I'm definitely curious how much more details (if any) I will be able to glimpse.

It seems to be getting a bit easier to pick out, or maybe I've just had pretty decent seeing lately. -george Good question, George. BA has always avoided detection - for me. But, it is easy these days. It must be getting darker, or it would have been this easy last year when (only?) I failed to see it. Would like to look back over my sketches to see if I inadvertently captured it. Asking Dean about BA last fly by, he might have mentioned it was difficult. Apparently, not anymore. Sasa, get that ED 130 out there! Or let me borrow it.

It was clear that we would be soon covered by inversion clouds, so I took out just small refractor that I know temperates quickly, AS80/1200 (sorry, no ED130 yet). It was worth at the end, as the GRS was just on meridian. I could spot quite some details (including the junior spot, it is still visible even in 80mm, although it is more just some wave on the belt then individual spot): Post Extras:       Asbytec Guy in a furry hat Reged: 08/08/07 Loc: La Union, PI Re: Jupiter 9.11.2012 - first time seeing oval BA [Re: Sasa]       #5528721 - 11/19/12 08:17 PM Edit   Reply   Quote Quick Reply   Second time spotting it? It is so much easier this time around. Not sure why. Yes, most times it appears, to me, as a bump much like you've presented. At the best moments it seems to tighten up and near the meridian that smaller dark oval can be held (as a distinct, tiny spot or as a slightly darker patch) for as long as the seeing holds. Well done, thanks for sharing, Sasa.

It's fun to see this feature pass by the GRS as it zips around Jupiter.

It was quite easy to see in my 100mm f/13 and 100mm f/12 Achromat refractors. Also preceding BA, but in the SEB was a very bright white spot. Also some bright bays in the southern edge of the NEB, and a couple of large festoons. A thin equatorial belt also visible. Jupiter is a real joy to observe at the moment, so much going on.

I just came from another session. Unfortunately again short (about 20 minutes), the clouds were moving in again. I took only 80mm refractor out (I promise, I will take out something bigger at some point), still I was rewarded by nice view on GRS, junior spot and few other details in SEB and equatorial region: Post Extras:       Asbytec Guy in a furry hat Reged: 08/08/07 Loc: La Union, PI Re: Jupiter 9.11.2012 - first time seeing oval BA [Re: Sasa]       #5549379 - 12/01/12 08:44 PM Edit   Reply   Quote Quick Reply   Sasa, that's an amazing sketch. That you captured that amount of detail in an 80 Refractor speaks to both the scope and your skill as an observer. I applaud you.

I guess it is just Jupiter which makes the show. The details, bands, red junior, etc. are showing nowadays quite some contrast. There were only 2 difficult features that I spotted that night, the most eastern and most western festoons were just ghost. Other features, including the middle festoon, were more or less easy to see. One just had to wait a little bit for calm moments. Concerning the optics, AS80/1200 is indeed a nice scope. Especially for short sessions like this. I also own 80mm triplet (Lomo 80/480mm), which I bought for astro imaging. I found the AS80 is providing sharper images: here.
