I opened the box that my telescope came in a couple of weeks ago. I inspected my telescope and was all ready to calibrate it. It was then that I found out that the battery in the sight had died. The sight had turned on either while packing or during the move itself. The battery is one of those round flat batteries that you can’t find even in the states–much less in Germany. Looked online–found none. I maybe waiting until I return to the states to look at the stars.
