Jupiter: NEB happenings


John

Recommended Posts

I've been getting a few glimpses of Jupiter over the past half hour in what is a mostly cloudy sky. When the giant has shown it's face, apart from a nice GRS transit in progress, I've been fascinated by the activity showing along both the N and S edges of the N equatorial belt. A couple of massive and very dark festoon type things on the S edge plus all sorts of knots, ripples, bays etc. Very interesting :smiley:

The SEB is rather dull by comparison, apart from providing a nesting place for the GRS.

Wish the clouds would give way to some more clear patches and let me have a longer look :rolleyes2:

I have just come in from first light with the Vixen ED103S John and observed the same on Jupiter,
quite a decent pair of dark festoons as you say, quite prominent.

Love my new scope by the way, I cannot stop grinning,
but I had to come in its early work in the morning.

This evening has been first light for the FC100DC, and I too have seen this detail on Jupiter.

What scope are you using. Hubble? Or just the Hale? :D 

With my new refractor I could just about make out the separation between the equatorial belts and GRS.

Just the ED120 John - not big enough even to be a finder on the Hale :smiley:

Was the GRS at about 7 o'clock? (in a correct image)

If so I fancy I glimpsed it today.

Close - about 8 o'clock, refractor view about an hour ago. Just gone off the disk now.

I saw the two dark bits on the northern equatorial belt that were hanging out of the southern edge of it. I thought I saw the grs but  could not confirm it in sky safari so assumed I was seeing something else. But when I read this I double checked and I did see it, I just checked the wrong limb on sky safari because I (unusually)  had a mirror diagonal swapping left for right.

My brain confused  -I meant about 4 o clock with teh raci, so that would be 8 in a frac.

Looks like I may have seen it with the Mak but not with the little frac.

Makes sense. I could never see the GRS convincingly with my old Tasco 60mm frac but I got it the other night with the TV Ranger 70mm ED. Better coatings and glass in the TV of course.

Recent views of Jupiter have been fantastic. I called my wife out to see the GRS this evening. She had no trouble seeing it which was her first time. A really distinct orange colour compared to the rest of the planet. I’ve been enjoying those two festoons too. I feel like they may be getting bigger. I seemed to be able to follow them further towards the centre of the planet compared to other sightings.

I have been viewing Jupiter for most of this week but cannot get much more detail over some colour banding - even then it is hard to make.

I know that conditions here are not ideal - whichever way I face I am looking over roads or houses and Jupiter is low anyway, but I was hoping for more from my Mak.  Can I ask what sort of magnification you guys are working with to see such detail?  I tend to find anything over about 160x (12mm EP in my scope) and the view breaks down and details go fuzzy.

p.s. here was my attempt to photograph taking some measurements of the size of Jupiter and the angles to the three nearest moons with the mc-127

Where did you get your measuring EP ? I knew they made them but who and what exactly are they called ? Kinda a senior moment right now :(

My views are over houses, roads a school and a police HQ generally.

I'm finding 130x - 180x is working well with my refractors from 100mm to 130mm. Your 127mm mak should do well on Jupiter at 160x ?

I've been using an OpticStar 90s Gold, 90mm f/8.8 (800mm) refractor so far, the best eyepiece I've got for Jupiter is a 1.25" 6mm wide angle, so 133x but a good field of view. For imaging it , I've been using an AS120 without Barlow on minimum res, but I'm planning to try it out with a 2x Barlow sometime. 

This is the best result I got so far, and it's essentially the same view as I can see visually, although little bit more contrast. The 90s Gold is a beautiful telescope! :) False colour really isn't bad, either.

Thanks !! Now i remember why I don’t have one :( , cost is heavy in USD . However back in 2003 i could gave got one for less than $100.00 USD . 

Meade do one but don't know if it's any "cheaper".

Just found one place under $100.00 . Not that I actually need one now since full retirement is in the future but it would be neat to have it in my collection !

Thanks - I stayed out later than normal last night (for me 11 is late as I need to be reasonably awake at work) and the view was better.  I also think my eyes are getting better at seeing things as I spend more time with the scope.   I saw more banding last night and could see the GRS - was pretty chuffed with that.  My best view was using a 12mm BST eyepiece giving a mag of 158x.  I tried my new 18mm ortho and the view was about the same, albeit smaller.

That pic is excellent - certainly shows more detail than I saw last night.  I think I need practice, which means more time in the shed / at the scope :)
