Jupiter 26.01.2003 - Processing details

Here is video file created from 25 best frames from my source AVI file (02:12 UT). The air turbulence in my "balcony observatory" doesn't allow me to achieve better quality of captured video (see also Jupiter photos quality and seeing conditions).

Jupiter. 26.01.2003, 03:12 (02:12 UT)

25 best frames from source AVI file
(generated by K3CCDTools).
The video is coded by DivX5 codec.

Result image
Stacking 104 frames of source AVI
Gamma 0.80 + unsharp mask (4,0,350) in K3CCDTools.
Realign color planes + color saturation in Maxim DL Demo

Playing with K3CCDTools and Registax

I tried to extract from AVI as much information as possible. I tried to do my best in K3CCDTools and Registax. Here are the results:

  K3CCDTools Registax
Stacking result
(210 best frames)
Difference of stacking result
Subtracted pictures in K3CCDTools:
K3CCDTools - Registax
The difference is amplified by factor 8
and resized to 200%

The difference is very slight,
you must adjust your monitor setting to see it

The same difference amplified
by strong histogram stretching
Processing results

My personal conclusion:
Unsharp mask is showing in some areas
better details, but on the other hand,
the result image looks less sharp than result
of wavelet processing

Gamma 0.80
Unsharp mask (4, 0, 700)

Gamma 0.80
Wavelet processing
