Primary Mirror Mount Design

The team has completed a preliminary design for the primary mirror mount.  The design utilizes a floating 9 point mount composed of three brackets with "V" grooves underneath.   The brackets interface with the existing holes on the open back of the light-weighted primary and exactly constrain the primary mirror.  The PM mount will have 3 differential screws allowing for tip / tilt and piston adjustments.

Mechanical Design Update

The overall mechanical design has been updated to match vendor parts as they keep coming in. Below is a rendering of the most up to date CAD model.

Procurement/Construction

Currently we are procuring parts in anticipation of mechanical design completion in the next few weeks. We appreciate all the support of our sponsors, faculty, friends, and family and cannot wait to unveil our completed scope.
