After a very frustrating night, I turn to my friends here in hopes of guidance.
I had (according to sharpcap) "good" polar alignment (not sure if they rate higher than that in Sharpcap). However with good polar alignment, I could not image for more than 4s without star streaks. When opening up PHD2, I see massive movement on the graph. Some images below.
At first I assumed I must be super off balance in terms of weight on my mount, but after triple checking my equipment was perfectly balanced.
Equipment in question
Williams Optic Zenithstar 61
Atik EFW 2.2 Filter Wheel
So the total weight is very very low, additionally I have used this same equipment many nights without issue.
Any thoughts as to what is going on here?
