Any interest in more planet videos/stacks to process?
I caught some decent colour video of Saturn last night, just wondering if there is any interest in uploading it for others to practive processing on?
About 5000-8000 frames or so.
A quick stack from each is attached.
If there is any interest I'll upload them, it takes a few hours, so let me know.
The PNG file (the blurry one) is the result of a stack and is in 16 bit, so you can load it into registax and have a play with wavelets or deconvolution while waiting for the .avi to upload, it will be about 4 hours according to dropbox!
Anyone know of a faster online storage system for files of over a GB in size?
I like the colours Paula, you might be able to stretch the histogram a bit more to give it a bit more punch.
Luigi, well done, your stack is better than mine (I didn't choose enough alignment points). I reckon you could sharpen it up a bit more with the wavelets.
Ivan was kind enough to share his Saturn processing steps, you could try a wavelet setup similar to his and see how it goes.
Like me he does his stacking in Autostakkert, he uses more alignment points than I do and gets great results:
Or you can do the whole thing in registax, and just try Ivan's wavelet settings.
Ivan, Asimov (John) and Damian Peach use Autostakkert for the stacking part, and that is a good set of references, so I reckon it would be worth anyone's time to give it a go.
I've had a go at processing the AVI. I must say, it's harder work with ordinary data like this. So, I'd suggest if you can get a result you are happy with from difficult data like this, then you will be thrilled when you capture some magic data on those elusive night of good seeing!
Here's a screen capture of the AS!2 alignment points and settings:

Thanks for the detailed processing steps.
Sadly, that is the best seeing we've had here in months, it is usually much worse!
Part of this exercise was to hopefully get some expert processing applied to average data to see what could be done. Also to let people know what they can expect from their captures and know whether to blame the data/capture or the processing for the results!
I'm hoping to get some good data in Armidale.

Peter, you're doing a good thing. It's worth practicing on difficult data.
And it's also worth trying on every opportunity to get good data. I reckon you will have noticed that most of the leading planetary imagers are out there pretty much every night, so when the seeing comes good, they get good data.
So it's also worth experimenting with your capture settings to see what eventually gets good results and what doesn't, so you can make the most of the seeing when it finally does come.
I'm not sure of the nuances of capturing in colour, but I reckon this AVI is a bit dark, so is more affected by noise than it would be if it was a bit brighter. Also, that would have made focusing more difficult. Maybe try knocking the frame rate down a bit, or reduce the f.l.? Undersampled data (i.e. data that has finer detail than the pixel scale) responds well to upscaling later.
In the end though, the seeing makes or breaks it. Still, all good stuff to try.
I liked your first one better. Even though this does have more detail, the smoother appearance of the first one is nicer, I think.
Both very nice results. With that technique, now all you need is some special data!

TyVM Ivan! Your result is fantastic, It's fantastic what can be done with the same data set.
I'm on a random weather streak I'll try to do some images myself soon
