Does he have a website for these ?

Theres a few questions I would want answered if I was going to buy one.

1: how big is it?

2: Height of the axis of rotation wrt the centre of the top board. It is important for stability reasons that the dobs centre of gravity is below the axis of rotation. This will vary according to designed latitude.

3: How long will it track before requiring a reset?

4: How do you reset it?

5: Motor step size in arcseconds rotation of the top board.
This is important. If there is not enough gear reduction, discrete steps of the stepping motor may be visible at the eyepiece when observing at high power.
