I have one of these excellent polar alignment cameras and ADM dovetail mounting adapters for sale.
With the adapter, you can attach to the mounting rail of any OTA, which means it can be used easily with any type of mount without the need for a mount specific adapter.

Comes in original tin with cable and screw-in lens cap. Does not include any other type of mount adapter.
Asking $375 plus shipping.
All questions via PM.
