| Title | | 'The seeing monitors: Instrumental noise and cross-calibration.' |
| Abstract | | These last years, several seeing monitors (DIMM) have been built almost everywhere, with a material that was intended to serve only amators of astronomy. In order to make a campagne of site testing in morroco, we have built our own DIMM in Marrakech university. To make our instrumentation reliable, we wanted on the one hand to measure the instrumental noise and the influences of defocusing on the values of the seeing; and on the other hand to make cross-calibration of several instruments while using various diameter tubes (C8 and C11), various cameras and also from different mountings. We are presenting in this communication the results of these various tests.
