which driver to use when guiding in Phd 2 with zwo asi 120 camera ?

[red dwalf]

hi all, 

i`m still getting some subs which are not too good and show slightly trailed stars, i`m pulse guiding with eqmod on a NEQ6 Pro and guide speed sidereal rate of 0.5 which i think is right for this mount, the mount has had a belt drive mod on it.

i`m using the ZWO ASI 120 mm camera, usb 2, and i`m wondering if i have been using the wrong driver in phd 2, i seem to have a lot for this camera to choose from,

the one i`ve been using is the zwo asi camera, but i`m wondering if this is my problem as i`ve tried everything else to get better guiding, there are two other choices, ascom camera chooser, 2. asi cameras ascom, and the one i`ve been using , 3. zwo asi camera.

also should i be selecting enable server, picture 4, with all of these drivers when pulse guiding ? 

many thanks for the help, i`m very confused with it all.

I find "Windows WDM webcam" is the most reliable when guiding with my ASI120MM. You will need to play with the camera settings but I use a gain of 95 and exposure of 1 sec.

Thanks james, I'll try that one as well.

Do you still need to tick enable server james ?

[james_screech]

You only need to enable the server if you are using another application that needs to control PHD (for dithering), though it will do no harm to have it enabled even if you don't need it.

OK thanks, I do either using nebulosity.
