Image issues despite good tracking

I've been having some issues with my images since getting the dedicated astro cam and filter wheel setup

I'm finding a much larger proportion of my images showing elongated stars. Normally I would think this was a tracking issue but I am getting a tracking RMS error of 0.6-0.8" most nights, which is well within my pixel scale of 1.15"/px

I am wondering if it's a balance issue - I am using the standard WO 245mm dovetail for my Zenithstar 73 and I have definitely found that I am heavy on the focuser end, and I can't move the scope any further up due to the length (or lack of) on the dovetail.

Anyone have thoughts?
