after many attempts I realized that taking pictures during the day with the sun still high is useless though some say the opposite. Even if the planet is more 'high daylight absorbs the UV! I wait for the sun to set so 'the telescope, which is located in the basement, maintains a temperature more' lower than outside when I take him out and the turbulence is low.
In addition, IR have never been able to resume details. These in my opinion are seen well only in UV. The Astrodon filter is slightly better than the old Baader (slightly!). With both already in recovery i see the central area or arms laterlai more 'dark.
I work with Celestron Ultima Barlow lens Apo 2x, then at about 8-9 meters focal length. If you do not use the barlow the planet is much more 'small and the details dilapidated and poorly defined....
