This post aims to show that seeing is one of the most important things for planetary imaging with high resolution.
3 photos of Saturn were made on 3 consecutive nights (S1, S2, S3) always on time 23:00 UT.
In all the setup used was exactly the same:
C14 Edge Telescope
Qhy 5P II Color Camera 5Mp and 2.2 micron pixel
Astronomik L filter
Capture program EZ Planetary Qhy own because the camera does not rotate on the Fire Capture
Stacking the AS!2 But paragraph of stacked frames varied.
Processing using Registax 6, Photofiltre, Irfan and Fitswork
Below the data capture each photo for analysis of colleagues.
photo S1
Taken on July 19 at 23:00 UT
Stack of 1367 frames
Astronomical seeing: Idex 1: 3 Idex 2: 2 Resolution: 2.36 arc / sec

Data obtained from the website Meteoblue may therefore have some incorrect prediction by the variability of parameters.
http://www.meteoblue.com/en/brazil/weather-porto-alegre/seeingI know that the photos have their defects to that in none of them was seeing really good and also because the author has its shortcomings. It is also not work with scientific rigor and let colleagues analyze and interpret the data since my intention was summed up in only a good seeing evidence that is crucial to a successful outcome.
