Spanning just over one hour :

Very good indeed, great colour and detail nice one.

Nicely done Stuart as above detail & colour look great!

[neil phillips]

Nice animation Stuart. the middle sections look like where the seeing calmed the most

[Space Cowboy]

Thanks Tim & Simon!

There was a 10 min sweet spot Neil as you say when seeing improved enough to see detail inside the GRS and from this I got the 3 winjuped stacks to produce the best image. Gotta love OSC cams as they are the best for variable seeing and animations IMHO   I would love to get a full rotation but that may be a pipe dream as the most I've ever got was 3 hours.

Brill!

[sharkmelley]

Very nicely done!

Very nice animation, always nice to see the variation in seeing.

Great animation Stuart and some nice detail over that sequence.   Those axial perturbations are definitely going to get the scientists worried -  

[Space Cowboy]

Thanks again guys!  Ha ha yes Jake there seems to be some kind of external gravitational force causing that wobble....maybe a black hole?   Seriously though its annoying...even when I use winjpos to rotate each image there is still a wobble (these were done in IA).  Without spending hours trying to fine tune each frame by hand I'm at a loss to fix the field rotation 100%.

That is fab! Thanks for sharing.

[Space Cowboy]

Thanks Stuart!  Here is a smoother version with all the frames aligned in winjupos and a few extra frames generated to fill in the gaps :

Really very nice indeed Stuart. Top job.

Great job Stuart.

I have been looking at Winjupos but personally find it difficult to fine tune the equatorial region exactly, as from what I can make out it's only possible to rotate initially in 10 degree increments? Is this correct Stuart or am I missing something? I've not done any rotation work but would think that this lack of  fine tuning may have something to do with that wobble?

[Space Cowboy]

Not sure what you mean Harvey. All I do is set the auto image outline in measurements save the ims file and then open in derotation of images and generate the derotated image which flips it with north at the top.

[astroman001]

Great result. Good consistency across the animation.

Thanks Peter!

[neil phillips]

That is fab! Thanks for sharing.

Ive seen worse wobble on EQ mounts  good stuff.

[Space Cowboy]

Thanks Neil still annoys me that wobble lol

[PhotoGav]

That's a great animation. Is it made of just twelve images?

I hope to have a crack at a Jupiter animation tonight, if conditions allow. I have been considering how many frames, how often, how much disk space and how many days to process it all! If I manage something anywhere close to what you have here I will be one happy planetary imager!

Hi Stuart,

Very nice animation. The second go did improve the slight tilt that was in the first.

Thanks

Cheers Gav! I think there were 17 images altogether though a few were generated in winjupos by combining 2 images to produce a 3rd one inbetween.  If you want to collect  images over several hours for a animation then taking a capture every 10 mins should be ok depending on how much disk space you have. You want the avis to be at least 2 mins long to have enough frames to play with so thats at least 1gb per capture. Using Autostakert you can batch stack the avis which saves time though I do process each image individually after that.

Thanks Dror good to see you back on the forum!
