Thanks everyone for your inputs.

I'm using this scope
https://www.amazon.c...r/dp/B00PUXC50U
with this camera
https://www.amazon.c...a/dp/B01C5W2KIK
They are both rebrandings for the asian market.
I had PHD detect the pixel size (it's set on 7.5, and on amazon it says 3.75 x 3.75...is it ok?), and set 240mm as focal length.
I already reset the whole thing (both mount and PHD) many times, but I'll give it a new try.

Thanks, after resetting everything, I'll try with those settings.

I honestly don't remember, but I think those 4 graphs were from different stars in the same area of the sky.
I never go too high in the sky because right now I'm using it on my balcony, and there's the roof.
Drift alignment may be one of the issues, but since I started trying to take DSO pictures, even before guiding, I've always had this crappy RA drift, very evident, compared to DEC.
One more question I'd like to ask, with this camera I have to use ASCOM toupcam driver, and ToupST4 (ASCOM). Which is fine, but the problem is that like this (as far as I understand), it's treated as ST4 and not ASCOM, and for example, when I use the drift allignment function, I will get the dotted circle instead of the normal one (which means it's less precise). If I use any other ASCOM named thing under "mount" it will either not work properly, or not work at all (giving me constant errors).
The setup is: USB port connecting the PC to the camera, and phone-like cable connecting the camera to the mount (auto guide port).
If impossible it can't be helped, but is there anything I can do about it?
Thank you again.
