To fine-tune the focus of the guide camera with ASIAIR, you have to replace your main camera with the guide camera, as ASIAIR doesn't provide a direct way to display the guide camera image (or I missed that option).
Please follow these steps:
- IMPORTANT: Before switching cameras, turn off the ASIAIR and wait 30 seconds before turning off the power switch.
- Switching cameras by disconnecting the main camera.
- Connect the guide camera to an USB port on the AISIAR.
- Select the guide camera as the main camera (you can leave the other settings as they are).
- Power up the ASIAIR again.
(This screenshot is not quite correct, instead of the ZWO ASI294 you should select the ASI120MM!) - On the right side of the main menu, click Focus.
- The Focus screen opens:
- Manually adjust the focus of your guide camera
- When finished, turn off the ASIAIR
- Reconnect the main and guide camera, select the cameras in the drop-down menus and turn the ASIAIR back on
- IMPORTANT: Don't forget to set the correct main camera parameters such as Gain to the desired value!
