Your obviously using a 50mm guide scope in the offset shoe bracket. I started with that option but changed to a centrally mounted 60mm guide scope on a solid mounting bar on the tube rings , much more rigid system especially with imaging focal lengths at 1000mm +
In regard to your elongated stars what are your Ra and Dec numbers ? Are they close in value or significantly different ?
Is your polar alignment tight ( less than 1 or 2 arc minutes )
Maybe you have some high Dec backlash ?
Try the guiding assistant in PHD2 it will give you plenty of data to evaluate any issues

I am also using a 60mm guide scope. Polar alignment is always within an arc minute, so no issues there. I’ll check the numbers and run the guiding assistant. My opinion is that it might be nothing to do with guiding, but might be to do with tilt, as I get elongated stars several subs in a row, but the issue then fixes itself as the OTA rotates. Either way, these little issues are slowly getting ironed out one at a time. Just need to fix this one soon!
