I'm setting up my Nexstar 102slt and am struggling with the allignment. I choose skyallign and fill in the coordinates and the time, etc. Then i have to choose 3 bright stars using the arrow buttons. This is where the trouble begins. When pressing any of the arrow buttons the telescope doesn't move and starts 'initializing' and i have to start all over again, which is useless as i can't get past this step. This previously didn't happen. This makes it impossible for me to allign the telescope or even use it. Do you guys have any solutions? I have already tried reseting the factory settings.
