Our main imaging telescope is a 9.25" (235mm) Celestron EdgeHD SCT on a CGEM mount.  The telescope has several modifications and peripherals to help setup the telescope quickly on an observing night.  Without an observatory, like many amateurs, setting up and polar aligning as quickly as possible, is the key to maximising the imaging time.  The single most effective improvement was the permanent attachment of a PrimaLuce Lab EagleS telescope control computer and power bridge.

It is not often that people share details of their set-ups. Thanks. I'm going to look into the Eagle S computer in more detail.

David, I think the EagleS is a discontinued product but replaced with the latest iterations of the Eagle computers.  The real advantage is that by attaching the Eagle to the telescope you can use short USB data cables from the camera and mount etc to the computer.  It is also a power bridge so that short power cables can also be used to connect equipment.  That removes the need for multiple power and data cables to trail from the telescope.  A single power cable trails to the ground.  I use a single ethernet data cable to connect to a remote computer although the Eagle creates ts own WiFi to allow control from tablets or remote PCs.  It is worth looking at to see if it would bring benefits to your particular setup.
