How to Test the Error & Accuracy of EQ Platform Build Video Series E07

This Video is episode 7 from the EQ design and Build series, the final and concluding episode.
In This Episode, I have Shown how i have measured the errors and accuracy of my EQ platform, as the platform was designed for 24deg North Latitude and also how i changed my Drive mechanism froma M12 screw design to a ball bearing lead screw drive for better accuracy.

If you own a non motorized or non GoTo Dobsonian telescope then you might have faced the hassle of adjusting the telescope again and again,
as the target slips away from the sight, breaking your back. Don't break your back, make a equatorial platform for yourself and live in peace
and also venture into initial level of astrophotography with a tracked long exposure photo, off course it will not be as crisp as an German equatorial mount with PHD2 guiding, but you get the point.
