I am trying the above product and can not get the drift alignment to work. I set a long exposure and click the drift align button, the live view appears in grey as i expect it should and the timer starts but it does not take pictures or overlays them so that the star track can be seen. I also have no drift end button. The only button that is operating once i start is the abort button. I have also selected the video button that starts but produces nothing. I have searched the web and the support pages for detailed step by step but can find nothing can someone please assist me.
