Hi,
I am out there to take photo's. It takes me roughly 40 minutes to get a reasonable polar align on my scope/mount as I have to setup afresh each time in the park. Now, I could spend a few hours doing it and try and get it exactly spot on, but whats the point as after my imaging run i will just pack it all away; and with the autoguider I get nice round stars.
I rely on the autoguiding to allow me to do 5 to 10 minute subs on an EQ6 with a 600 mm FL scope. As Ponders says it corrects my polar alignment error and gives me more time to image. Maybe if i had a permanent observatory (and a better mount) i woud spend more time polar aligning.
You are already spending a lot on an Atlux, a QHY5 and a small guide scope isn't all that much more.
By all means though, try it first and see how you go, then decide if you want to get an autoguider.
