Have you considered an EQ platform? For a 12.5 inch scope the cost is probably somewhat less than an EQ mount. Seems like a good way to retain the portability and stability of the DOB and still get tracking.
My guess is that your scope is too big for the Atlas mount. Your scope must weigh 60 lbs and be about 60 inches long, its a biggie for an eQ mount..
