Duncan that is fantastic. Wow !!!! That has given me a kick up the back side to get learning.  Any idea what causes the dip in luminosity in io a few frames in?

Fantastic animation!  Good detail and colour.  The red spot and a moon!  Really well done!

Thin clouds, also the first couple of frames.

BTW it's composed of 25 frames from 60s captures at 10fps with 1min intervals keeping 40% of the best frames. The animation shows how fast Jupiter is rotating! The elapsed time is around 1h15m. Next step is to master WinJUPOS derotation :}

Very smooth Duncan. I like it, John.

Excellent effort, I think we need another imaging session on your planetary workflow before you escape to France permanently!

Crikey Duncan, that really is a superb effort and there is just so much detail.  That has to be your best to date.

That ADC is certainly doing the business.

I'd agree with that, have you got a stacked "still", there must be more detail than in your previous images.

Glad you said where you took it since you are in two places these days lol.

A single image made from the 50% best frames on 60s capture @10fps. There is even colour and possibly features on Io, I didn't think this was possible with my scope.

That's about a hundred times better than my best effort :(

Great image and animation Duncan
Title: Re: Jupiter with WinJUPOS de-rotation
Post by: The Thing on Jan 30, 2015, 15:18:34
First attempt at this. Same processed images as before but utilising WinJUPOS to de-rotate the images and so combine them despite the images being taken over more than 1 hour which would normally result in smearing. Resulting image tweaked in Registax.

Hi Duncan, Nice but I think I prefer previous - this one is starting to get that 'overprocessed' look (at least to me) - looks like there are some 'ringing' effects going on - it has sharpened up the banding details though..
