Hi Folks
No the alt bearings do not collapse on the 15". Originally I was keen on this and Peter was happy to pursue it. A few design concepts were drawn up for collapsible bearings but the connection points for the 8 truss pole design proved problematic (easier with Obsession's 6 truss pole design). But the 8 truss pole design with SDM's classic stability/rigidity was what I was after in a compact design, so a compromise had to be made. Peter did have a close look at collapsing the bearings and I think if this was a requirement for your scope he would take another look at it. After all he is a genuine problem solver and superb craftsman.
The servocat was a no-brainer for me (other than cost). While there is a lot of 'fun' pushing around a scope, not to mention a great way to learn the night sky, the nature of my work means that I 'never' have enough time to observe so I am keen to get to what I want to look at quicker - that's my excuse and I am sticking to it. And as John B mentions, I can always release the clutch and I'm back to learing the night sky. Just personal preference.
Cheers
Nix
