I've seen a pre-loved Celestron C6 at a very good price that I'd like to purchase for planetary and deep sky astrophotography. The OTA comes with the dovetail for attaching to the mount but no dovetail, or attachment points, at the top of the OTA; I would need this to attach the guide scope and camera and (optionally) a Pegasus Micro Powerbox. However, searching the web, there seems to be no easy solution to adding a second dovetail bar. Does anyone have any thoughts on how this could be done? I've also seen a couple of Skywatcher Skymax maks that have the same issue, so a solution to that would also be appreciated.
