Hi, I am wondering about the max exposition time you can take a photo with this.

Thx
Hi,
I am taking photos with a maximum exposure time of 4-5 minutes. Take in account that, because we are not pointing exactly the north pole (the Polaris is close, but not in the exact Celestial North pole (info below) ) this deviation will cause a appreciable shift in the stars trajectory if you trespass this time limit (or if you use too much zoom).
