I have been trying to focus my guide camera in my OAG without success. Setup is QHY9, QHY CFW-2US, QHY OAG and QHY5L-IIM. I have focused the main camera on a star with a Bahtinov mask and then turned to the moon for the OAG as it is a big, bright, easy target. It seems the camera is too sensitive as the moon is washed out or I need more in-focus on the guide camera as when I draw the camera out, the moon appears to increase in size, so I'm assuming in-focus. I tried a star field with out success as well.
I did this once before with my QHY9 and Starlight Xpress wheel and OAG, and the moon trick worked well.
Any tips and advice greatly appreciated. I'm in an obs so not easy to try a terrestrial object.
