Abstract
A tower and access platform were fabricated and erected for the Hobby-Eberly Telescope (HET) Differential Image Motion Monitor (DIMM). The 5 meter high tower exhibits a fundamental frequency of 43 Hz. The cost of the tower system, including access platform and enclosure was $12K US. The enclosure includes a unique application of an off-the-shelf truck accessory that serves as a shutter. The enclosure is ventilated, and incorporates a windshield to reduce vibrations that have proven problematic in the Meade Telescopes used for the DIMM system.
