I’m using the 10Micron GM1000 mount with NINA. Nina’s logs are warning that the mount’s interval polling is slower than the default 2 seconds that NINA expects. Sometimes the mount takes over 6 seconds to report to NINA.

Should I change the polling interval to 10 seconds in NINA and forget about it or should I take the log’s warning seriously and contact 10Micron (I already did that but haven’t heard back in several days)?

Since the polling interval affects more than one device, I am not sure what to do here.

Thanks,

Jerry

Yes change the setting as 2 seconds is far to low for any of the 10 micron mounts, that maybe fine for much less accurate mounts, change to 10 and forget

On a 10Micron mount, the polling interval is not a fixed, user-adjustable setting in the way it is on other mounts

Instead of a constant, repetitive poll, the high-performance HPS (High Precision and Speed) series uses real-time, high-resolution absolute encoders to instantly determine the mount's precise position.

The mount's built-in intelligence controls and corrects tracking errors based on data from the encoders and a pointing model, which is a much more rapid process than the traditional polling used in standard autoguiding. The user-defined settings in the 10Micron ASCOM driver and external guiding software like PHD2 affect the timing of reactive guiding commands, not the mount's internal polling.

Thanks AstroStew for this valuable information.

Would the other ASCOM devices (camera, filter wheel, flip flat cover) be negatively impacted by increasing the polling interval to 10 seconds or does it not matter?

They have no bearing on the control of the mount, so should not make any difference to those items

This is incorrect. Nina's polling interval does affect other devices. When I set the polling interval to 10” the autofocus routine took over 4 minutes to complete. When I brought it back to 2” autofocus completed in about 1 minute & 35 seconds.

As you correctly pointed out, my mount gets its tracking data from the encoders and from a good model, which I made a while back.

I'm going to ignore the log's warnings as they have zero affect on the mount's performance. From the information I gathered, 10Micron is very slow to upgrade its ASCOM driver to the newest ASCOM standards, which may well be the cause of these unnecessary warnings.
