Yeah, I've ditched the webcam (it was all of $18) and polar aligned using the guide scope, which is an Orion 50mm mini, coupled with an ASI120MM, so it's all good. After a bit of fiddling about it's telling me I'm now within 1 minute in both axes. Hard to get better than that. Of course, I tried it a second time and the results disagreed, telling me I was a couple of minutes off, but I'm happy with that level of accuracy for the time saved. If I were up at the dark sky site I'd then drift align.
I'm a bit worried by cone error, as I can't guarantee the guide scope is absolutely parallel with the main scope (I'll adjust it when I go back outside - I'm having a cuppa now). The instructions seem to think that's not a problem.
I think I'm happy with that. It's good enough for any mucking about I'm going to do in light polluted Melbourne.
We learn and learn again.
