Do a quick test of your polar alignment
Pick a bright star in the east at 40 to 60 degrees Alt
Slew to and centre it , lock on and then track unguided on that Star , perform an unguided 60 sec sub frame.
Check sub frame zoomed in , if Star is nice and round and not bloated or elongated , eggy etc.. then you PA should be good ( generally good test up to 1200mm focal length which it what I image at with my Newts ) If not , you have some work to do to get your PA error down
Also in PHD2 it’s best to start guide camera exposures at 2 sec or even 3 sec ( not 1 sec, have a read of the manual it’s worth gold ) as 1 sec guide exposures this are too restrictive and can cause you to “chase the seeing” on nights where conditions are not so good.
Just a few things to start with …..

Cheers
Martin
