Here's another processed image from Wednesday morning, this time (for something different) I only processed the green frames. I was looking to bring out some more contrast around the GRS and all the turbulent cloud nearby.
This is 400 frames out of 800, processed in Registax and Astra Image. Image has been enhanced to bring out details.
The slightly "hard" edge on the rhs of the image is most likely caused by rotation / alignment gremlins. Over the length of this sequence (90 seconds) Jupiter rotated about 1 degree. In the centre of the image this comes to an offset of about 3 pixels. The alignment software has kept the image centres aligned, so this 3 pixel displacement shows up on the planet limb instead, pushing the latter frames off to the right.
- crop, gamma scale (again), smooth with contra-Harmonic mean filter,
resample down to final size, LR deconvolution 20 turns radius 1.3,
unsharp mask Medium x 1.7
Paul, I didn't mean that this processing sequence was better than another one.. actually I change what steps I do, and what values i use depending on how I see the results and the original frames.
I was only giving it as an example because someone asked if I used deconvolution as part of the processing. It's not unusual for me to try several different settings for each of these steps until I find the one that does the "best" job - subjectively!
Thanks Anthony, I actually found that this method worked a lot better for that particular AVI. And yes I can see that different things will work for different images. This gave me another technique though and I really appreciate you taking the time to help us lesser mortals.
Don't be so modest, even though this is my first season imaging the planets, it has been made a lot easier by the help that you and others have given. This makes a big difference to the enjoyment of the hobby and also lets me help others who are going through the same thing.

And thanks for the processing details.
