Auto guiding

Neoprog

Hi all.
I use a ASI120 Mini Mono with a ZWO Mini 30/120, an Asiair+, an AM5 and a Skywatcher 72ED or a C8.
I've problems with auto guiding.
It can work very well during 1 or 2 hours and sunddenly it losts the stars.
The camera config seems ok calibration steps 1709, exp 2s, Gain high.
Any idea ?
All the best

Neoprog Hi. Can you give more details about the problem you encountered? Was there no guiding screen? Did you take a screenshot of the screen at that time?

Asiair losts suddenly the stars. On the graph I’ve only verticals bars. The camera still acquire images and there is no fog on the guide télescope.
No picture sorry.
Thanks for your help and happa new year.
