I was able to charge the on board battery and research how to use the scope the same day I received the Nomad and was taking photos that same night. My 28-70mm zoom lens no longer has star trails using the laser. My 400mm requires pretty precise polar alignment with the scope but once set, I have no issues pushing past a 30 second exposure.
I wish there was instructions on using the scope and a polar clock, it took me a while to find a good app to use with it. Currently using Polar Scope for Android to get the alignment correct.
