Getting a solid focussed connection with the OAG guide camera in the day time can be good. I focus on ships on the horizon. A little out of focus on the guide camera stars can be ok.
A quality OAG with a solid round dovetail which allows rotation of the main camera should not disturb the OAG connection.

1. Connectivity to the OAG is not always rock solid and it can slip sometimes
2. When I rotate the main camera the guiding needs recalibration which eats valuable time.
I went back to using a guide scope using the FMA180 which gave excellent sharp stars but now there is an imaging/ guide ratio of 1:4 this could be reduced marginally with the ASI 290 guide cam
Is point 2 above just something I have to live with? Any suggestions how to make the OAG connection more solid?
Thanks
