COM Errors

[Mark Theissen]

I have a setup with two telescopes each with an ASI camera.  The cameras are an ASI2600MC and an ASI6200MM.  I use one scope to guide the other and switch back and forth as necessary depending on which scope is best for a target.  I use SGPro to control the session.  Using the ASI2600 to capture target images and using PHD2 and the ASI6200 for guiding has been working fine.  I just tried to switch over and image with the ASI6200 and use the ASI2600 with PHD2 for guiding.  This has not worked at all.  I'm constantly getting "COM Errors" and PHD2 is crashing.  I uploaded a PHD2 log to: https://openphdguiding.org/logs/dl/PHD2_logs_8V7a.zip

but I doubt that will help.  I've attached the debug log for the time period.

I've also attached an event from the Windows Event log.

I can get the ASI2600 camera and scope to connect and loop in PHD2.  The COM errors occur when I tell PHD2 to pick a star for guiding.  I've updated to the latest ZWO Native driver and ASCOM and I get the same errors whether I use the Native driver or the ASCOM driver.  I even updated to the latest PHD2 2.6.11 dev4 version, hoping that would help, but it didn't work either.

After getting these messages, I switched back to use SGPro to take some images with the 2600 and that worked fine.  So it would not seem to be a hardware or USB issue but I'm not 100% convinced of that.

It’s hard to say what’s going on.  But using a 26 mega-pixel color camera for guiding is probably not a great idea.  The ASCOM camera driver is reporting out-of-memory conditions so it’s likely the native driver is having the same problem.
