How to tune the Lacerta MGEN 2 with the EQ6-R pro ?

[Francis Sneyers]

I have a lot of difficulty to use my new Lacerta on my old Newton 1480 mm. When I use exposuretimes of 10 minutes, I have little stripes, no stardots. I think maybe I don't use the right values. Can anyone help me with this please ? Here is a picture of yesterday evening with the Nikon D5100 APS-C . It is not cropped. Thanks for helping me. 

Here are de details:

Live view screen:  Gain= 7  Expos= 900ms   Treshold= 1 (of 2)   avg

 

EQ6-R pro:

Auto Guide Speed:  0,5x

 

In "Live view" I see the star on the little screen of the Lacerta handcontrol. When I go to "star search" the star is not there on the little window.

When I go to "calibration" it shows "star lost restoring mountposition"

Sometimes, he calibrates on a very bright star and I can use "autoguiding start" but the results are very poor.

De Skywatcher tracking without the Lacerta is almost as good, as you can see on the pictures.

Hopely someone can give me the right indications, I would like that very much,
