I could not use the PHD new equpment profile wizard to establish a profile for the guide camera with both a ZWO ASI main camera (ASI6200MM in my case) and an ASI guiding camera (ASI290Mini), connected to the laptop. The main imaging camera pixel size was populated into the wizard until I disconnected the main camera.
Online forum literature says that this is an ASI driver problem, not a PHD problem.
This procedure that I used to make the new equipment profile was:
- Connect the 290mini to laptop.
- Do not connect the 6200 to the laptop.
- Connect the Gemini II control panel to the laptop.
- Open PHD, click the Connect icon in the lower left corner
- Manage Profiles: Delete any old equipment profiles
- Manage Profiles: New using wizard
- Guide camera: In dropdown, select ZWO ASI Cameras.
- Is camera already connected to PC? Yes
- Observe that the un-binned pixel size is 2.9
- Binning level: 1
- Enter guide scope focal length: 540
- Next
- Mount: In dropdown, select Gemini Telescope.net (ASCOM)
- Mount already connected: Yes
- Mount guide speed: 0.50
