The Ernst Hartwig Telescope
The 50 cm Planewave CDK Telescope located in the eastern dome is named Ernst-Hartwig-Telescope (EHT), after Ernst Hartwig, the first director of the Remeis Observatory. It was mounted on a 10Micron 4000 HPS mount in September 2013.
For the readers interested in the technical details:
- corrected Dall Kirkham type (CDK)
- spherical primary-, elliptical secondary mirror
- full compensation of aberrations
- focal length 3454 mm
- aperture ratio f/6.8
From the 1960s until the procurement of the EHT, no scientific observations could be performed directly at Remeis Observatory. With the new instrumentation, it is possible to revive a local scientific observation program. So far the EHT has been used for searching exoplanets with the timing method and as the main instrument for the MAPLE project.
