Nico, I did not manage to see the effect of the charge accumulation.
1. I tried slewing (west to avoid trailing due to backlash in the mount), stopping slewing and then taking an image. Could not see any trailing.
2. I also tried shining a torch through the telescope, removing the torch and taking image - again no difference.
Now, at the moment my camera is not cooled - could this be the reason I don't see the effect? How big is the effect? What is the best way to observe this?
