I love version 2 with the extra processing. What’s the Bortle scale at your site out of interest?

Not sure about the Bortle value - I suspect it is between 3 and 4 - I am above the Cowra main street light dome, so the southern view is pretty good.
I do spend a lot of time on polar alignment - I try to get the residual error down below five arc secs on the combined axes. With the AM5, it usually takes about 20 minutes.
