i have try this method this evaning.
It works well.
I used Capella as the sync Star.
After 4 times of corretion i send the iexos 100 into park position and then i made an 2 star allingment.
Then i let the mount slew to the pleijards (M-45) and they was in the middle of the camera picture.
I used the live view of my canon 1000d with an Tamron 35- 200 in the 200mm mode.
Next time i will try an star of Cassiopea.
