After tuning backlash and leveling base seems now it's tracking fine.

These planetary gears from OMC have a terrible backlash but enough for visual.

Thanks Khalid

OnStep provides for up to 1 degree of backlash (3600 arc seconds).

Good to hear that this is all it is ...

I have big backlash in az axis about 30arc/min.

Can i get better results or it's normal acuraccy?

Not sure if your question is about the length the object is in the field
of view, or the backlash.

You can easily tune the backlash using the daylight method described
on this page on the Wiki.

Hello, I've converted my 8" Dob with Onstep. yesterday I did some test, I did 3 star align (not perfect) but I managed to get a star at 150x during 20 min in FoV.

I have big backlash in az axis about 30arc/min.

Can i get better results or it's normal acuraccy?
