According to every star chart I can get my hands on, the directions to Cru-a and Eri-a are reversed. So I began to think I had a strange, wrongly etched reticle. Maybe even a rare once-off error.

Have a read of the instructions for Losmandy's polar scope and see if it makes things any clearer. Make sure you read all the way to the bottom because the old reticle was only good to 2010 and the new one is good to 2030.
