Yesterday I was have first problem with my ddm60. I was have star trails on images. My setup all the time stay in observatory, there are no changes about polar align, balancing etc. I have the same star trails with 5s and 50s and another exp. On DEC about 0 I have longest star trails, closer to NCP and star trails are shorter. Also during MLPT I was have error "Could not read GPS time". Without MLPT I haven't any error about GPS time sync. During every Autoslew startup I "Sync GPS Time". In Autoslew I have GPS status on green. What's wrong?
