Howdy
I am taking images through a 200mm F5 Skywatcher reflector, and i am hitting a slight issue, my focusing appears to be out, although my collimation is fantastic, PHD is giving me an osscillation index of around 25-30ish, which i am led to believe is quite good. i am taking my time to get focused, while it appears to look great at the time, the stars are kinda egg shaped, and i am wondering if this has to do with the grub screws making the connection with the QHY8 and focuser, get pushed to one side, that is, ill fitting.
What kinda symptoms could one expect with a rubbish focuser, and what would you recommend to combat this? adjust the focuser, or just get a new unit?
thanks in advance.
