Abstract
We present a test-study of the "seeing" at the Kryonerion Station of the National Observatory of Athens. We used a Differential Image Motion Monitor (DIMM) during July and October 2002 and found a median "seeing" of 0.68 arcseconds and 1.42 arcseconds, respectively. We also compared the technique against the Hartmann-version of the ESO-type DIMM method and found similar results within 0.05 arcseconds. For some reason, which is under investigation by international teams, the measurements of our ESO-type DIMM are underestimated by ≈ 10% compared to ESO-standard DIMM measurements. Simultaneous ESO-type DIMM measurements and standard gauss-fitting-technique measurements, taken with the Kryonerion 1.2m telescope (inside the dome) indicate that the "seeing", as measured by the telescope is by 1 arcsecond larger. The above tests were performed in order to calibrate, test and make a brief sampling of the "seeing" at the Kryonerion Station with the aim to move eventually the equipment to the Emilios Harlaftis Astronomical Station the site of the new 2.3m ARISTARCHOS telescope - for a long-term "seeing" monitoring. As a by-product of this project, a new DIMM Station became operational at Mt. Holomon, in the premises of the University of Thessaloniki, in 2004.
