For sale here is the HitecAstro Mount hub Ultimate. No longer in production I believe - it is an integrated controller for power, USB Hub, dew control and focus in the one device, that integrates into the Losmandy Dovetail system of your imaging system.
A very neat way of cable management and automated control of your scope/camera/dew control etc.
With this device you have fingertip control of your system to power components on and off, adjust focus and dew control, as well as assist with routing cables up and down from the mount (once setup properly you only need to run power and usb to/from the mount).
No longer in use.
