Hello!!! I'm asking about OnStep. I also have OnStep v5 for an EQ3-2, but the maximum exposure I can do with it is 10 seconds. If I set it longer, the stars stretch into trails with my Canon EOS 7D and Celestron AstroMaster 130. I set everything up very precisely. Do you know what the problem might be?

Hello! It might be an issue with polar alignment—are you sure it was set up well?

Yes, and what are you using to control OnStep?

From the phone, I control the shooting from the laptop.

And from which app? Personally, I use OnStep Controller 2.
