The Halfmann telescope

The Halfmann 35-centimeter telescope can just be seen through the bottom of the enclosure. The black object to the left on the same tower is a portable Meade telescope with Differential Image Motion Monitor (DIMM). To the left is the tower for the Advanced Technology Solar Telescope (ATST) site testing, on which the MASS-DIMM telescope will be deployed on remote sites. The final major component of the site testing suite is this DIMM, deployed as a MASS-DIMM (Multi-Aperture Scintillation Sensor DIMM).
