PHD2 will suddenly close when I am trying to run calibration assistant. I cannot send log files because PHd2 will not show any log files in the list when I select upload log file.

What should I try? I have already installed the latest release.

What OS are you running on?  PHD2 creates the log files during initialization so if you got far enough to run the Calibration Assistant, the logs are on your system somewhere.  We need to see those logs in order to help you.

The debug log shows you've gotten fouled up with the guide camera connection - you have PHD2 connected to the main imaging camera, not the guide camera.  The main ASI 2600MC imaging camera has a 26M pixel sensor so you are occasionally running out of memory in PHD2.  To help you get this sorted out, please update to the LATEST DEV release of PHD2, PHD2 2.6.13.dev8.  You can do that directly by downloading and installed 2.6.13dev8 from here:


You can also let PHD2 download and install it for you by setting these options on the 'Global' tab of Advanced Settings:

When the new release is installed, you need to create a new PHD2 profile using the new-profile-wizard.  In the dev8 release, there is specific assistance provided for people like you who are running with imaging and guide cameras from the same manufacturer.  You need to be absolutely certain you are choosing the guide camera.  It's pretty clear to me that you've probably never run the new-profile-wizard so you've really got a smoking mess at the moment.

For the short periods of time in the log where you were trying to calibrate before running out of memory, I can see you have lots of problems to resolve.  Be sure you have read the User Guide, especially the 'Basic Use' section.  More important, you're not ready to be using NINA or trying to automate any of this.  You need to get your PHD2 configuration fixed and then run the Calibration Assistant and the Guiding Assistant manually and get a stable guiding situation established.  You can't successfully automate a configuration that isn't working.

Good luck,
Bruce
