I use Maxim dl 6 where there is an option after calibration to guide on all the stars in the field rather than just the guide star. At one time I used PHD with but have found it much easier and more reliable. The other advantage is the point telescope here command. I have ASCOM pointing to The SkyX and Maxim links into this. I have T point add on which will allow very accurate polar alignment but also will correct any pointing errors giving a high degree of confidence. The other advantage of Maxim is the ability to use 2 cameras. I expect with the £/$ exchange rate this will be more expensive but is worth avoiding the frustration of spending hours centering the star.
