Does anyone know if the secondary cage on this can be set up so that the focuser is at a more traditional angle?  I know I asked this same question about the regular ES 10" and later found out that it had mounting points that allowed the cage to be rotated 45 degrees, but I don't know if the Costco version has the same capability and have not been able to answer by looking at videos.

 

Also, ES lists the weight of the scope itself as 44 lbs?  Is that really correct?  My 12" Orion only weighs 50.

The conventional truss  ES dob has a UTA that can be attached in multiple orientations.

I don't believe the Costco version can be attached in an orientation different than the one in the picture.

A drill, 4 new holes, and a tap would allow you to rotate the UTA, say, 30° if you wish.

But it doesn't come that way.

Yeah I checked with ES and they said the same thing as far as not being able to rotate.  I had guessed that the bottom ring could be removed and rotated with new holes being drilled.

 

I am still a bit put off by the weight. I mean the truss assembly is only 2 lbs lighter than the 12" Lightbridge truss assembly.  That is crazy.

It is not an ultra lite, it's a compact scope.
