focus cube or motor kit on secondary mirror

Post by gboyle »

Hi All
I have an old robofocus focus motor on the secondary mirror of my RCOS20 scope - the original focuser/controller had died.
I will attach a couple of images.
would like to switch over to a perseus focuscube solution but attaching the cube is tricky on secondaries and would love to see some example of how you have secured the cube in place so that it can marry with the pin/bearing at the rear of the secondary mirror.
can anyone send me some images of their setup on secondary mirrors?
thanks

Just keep the motor as it is and get our DMFC controller.
You can connect the Robofocus motor directly to the DMFC controller by using tht PEG-CMOT-RJ45DB9 cable.

or.. if you have the UPBv2 you can directly plug it into the motor output.
