Skywatcher Star Adventurer latitude base, available as accessory $89.00. Simple adjustment to align with main scope, carries 80mm Mak with ease. Works for me quite well, especially with the illuminated reticle.
(Pretty sure it will accept your Orion dovetail for quick release) My grandson also likes it because he can view through the Mak while I'm using the dob and we can discuss what we're seeing!
