I recently got Apertura 6" f/4 scope (below) and this is my first Newtonian system using tube rings.
Tube rings are attached to an 8.75" (~ 220mm) - long dovetail bar. I am thinking of adding another dovetail bar on the top of the tube ring, in order (1) to use it as a handle and (2) to move finder/guide scope to the dovetail. Is this a recommended way of using an extra dovetail?
BTW, I cannot find a right dovetail with a correct length (220mm) and hole positions - the distance between two holes on the tube ring top is 19mm.
Is there anyone who tried the same mod with this GSO/Apertura/TPO scope? Please share your idea and advice. Thanks!
