HEQ5 guiding problems #33860
Hi all,

After weeks of cloudy weather, yesterday it was finally clear. So I could test my setup for the first time. I have a mobile set-up :
  • HEQ5
  • Skywatcher refractor 120/600
  • Canon 700D
  • Guiding : ZWO 120mini on a guiderscope 50/160
  • Raspberry Pi 3B+

I have my HEQ5 connected by a cable between the handcontroller and the raspberry PI. When using the EQMOD - driver I set the handcontroller to PC direct. During photographing a serie I notice the HEQ5 stops tracking which results in a failure of guiding. As a consequence I need to recenter the object and restart the guiding. Sometimes it happens after 4 photo's, sometimes after one.

Any insights in what I'm doing wrong?

kind regards,
Gunther

This sounds like a tracking error caused by interruption in communications, not specifically a guiding issue. It may be your cable connection. Are you connected through a usb hub? Do you have a good quality adapter? Cheap ones can suffer in the cold. You can try the Synscan driver or Synscan legacy driver if you suspect it is a driver issue.

HEQ5 guiding problems #33878
My HEQ5 used to be very picky about power and would at times disconnect the serial port which caused tracking to stop. I added a second power connector that screws tightly and haven't had an issue since. So I'd recommend checking the power cable connections and batttery voltage at least. Also EQDir-cable would probably be more robust than running through the hand controller serial port as the driver doesn't like serial disconnects.

HEQ5 guiding problems #35093
It seems I found reason why the HEQ5 randomly stops tracking. It seems that the EQMOD driver is loaded with the option to stop tracking when the horizon is on its limits. When I unmark this option the HEQ5 tracks without a problem. I was logging the mount and I found following records at the moment the tracking stopped :

2019-02-16T09:37:47: [INFO] Setting Backlash compensation - RA=10 microsteps DE=10 microsteps
2019-02-16T09:37:47: [INFO] updateLocation: long = 4.72417 lat = 50.8297

2019-02-16T09:37:47: [INFO] Mount is parked.

Now during tracking I get the following messages :
2019-02-16T23:03:01: [INFO] Align: current point is 7
2019-02-16T23:03:00: [WARNING] Horizon Limits: Scope outside limits. Nothing to abort.

2019-02-16T20:33:52: [INFO] Align: current point is 0

So he still gives a warning, but he doesn't abort the tracking.

kind regards,
Gunther

Try resetting EQmod driver to default configuration and ensure time and geographic location are accurate.

HEQ5 guiding problems #48632
I have exactly the same issue.

It seems that the driver sometimes read some wrong position data, because the next readed position is correct again. This also happens due to parking mode and no movement. In KStars the position is jumping for a second to another place and then jumps back to it's original Position.

Here is my log:

I have to disable the stop Tracking option to, to avoid guiding problems ...
