Mirror Cells

Remote Collumnation

The remote collumnation feature is available installed with your order or as a kit for installation on an existing mirror cell.

Description: Two collumnation adjustment screws on the cell are driven by 12V gear reduction motors via a ¼ in. wide flat belt. Manual adjustment of the collumnation screws is still possible by disengaging an idler pulley to relieve belt tension. Control of the motors is accomplished by a FOB similar to a car key FOB. There are two buttons for each motor: up/down.

The goal of this option is to allow astronomers with a large DOP to perform fine adjustments to mirror collumnation fro the eye piece, while performing a start test.

(see start test instruction link)
