Re: Interesting Behavior with APCC Pro and Pegasus Astro UPBv2

Thanks for the response.
I’m using the latest version of the Pegasus Astro software for the UPBv2, so it sounds like I need to contact them regarding the temperature reporting issue. I’ve not yet confirmed that after switching back to Celcius, that it restores the unguided accuracy. I should be able to give that a try tonight.
As for the Advanced Sequencer, I saw it for the first time yesterday. I was expecting a UI similar to the original sequencer, which it’s not – but I think that it’s better. I really like to flexibility. I’m already thinking ahead to when Astro-Physics updates APCC to support the new few-stars tracking model that they introduced with the Mach2. It would be really cool to write a script to sample and plate solve 6 or 8 points along the target’s declination for unguided imaging, and then have NINA invoke the script at the start of an imaging session.

You may need to update your Pegasus software to fix this issue.
Older versions of the Pegasus UPBv2 console app and ObservingConditions driver will relay the Fahrenheit temperature to downstream consumers such as NINA or APCC when the console app is set to display units in Fahrenheit.
The ASCOM ObservingConditions interface specification specifies that the values for its various meteorological properties must be in SI units (ie, Celsius when it comes to temperature), so that is what APCC is expecting. Pegasus issued a fix for this last year so you might just need an update unless they’ve reintroduced the bug in a recent version.
This issue was even more obvious to those who have NINA set to convert the SI units too imperial for display. This caused NINA to convert the Fahrenheit temperature to Fahrenheit again, resulting in some outlandish temperature values being reported.
Aside from that, your description is quite an interesting depiction of how much temperature can alter the tracking of the mount under a model, though. Glad you were able to work out the cause. Hope you like the Advanced Sequencer, too. It is of course a work in progress but it’s maturing nicely.
