As someone who has very recently learnt how to drift align from a location with no clear view of the pole (southern, in my case), a few random comments:1. I've gone from an hour of stuffing around to 5-10 minutes for near perfect polar alignment.

2. Given you have a ZWO camera and a laptop, you would be crazy in my view to do anything other than use the 'drift align' process in PHD2.  You can do it using a visual eyepiece, but why bother when you have PHD2 there ready to give you an easy to understand graph and recommended adjustments.

3. You do not need ASCOM (etc) control of your mount ….
Bravo! this is a perfect drift-align guide.
