Yoshiro & all the folks who responded. & many did. It looks like a lot of people are interested in 10Ghz. Right now i am modifying the back plate of my 80CM dish to adapt it to the Ioptron 8200 gear box which is not designed for dishes but for telescope. If you are interested please look at Hans pa0ehg website it has been my guiding light. 
I need to download a moon planner which i can configure & understand & that is not obvious. 
Thank you Yoshiro for the VK3UM attachment very Helpful

Hi Serge 
You see the polarization offset between VE1 and DL in the attached llist as SPATIAL. It varies time to time and I believe your successful angle to set is -45. 
DL0SHF uses Vertical. 
Spacial offset can be known by F1EHN EME planner or VK3UM PLANNER. 
On 10GHz there is very little Farady rotation and no need to count.
