    DAG (Eastern Anatolia Observatory in Turkish) will be the newest and largest (4m) observatory of Turkey in both optical (VIS) and near-infrared (NIR) Owith its robust observing site infrastructure. The telescope is designedOto house 2 Nasmyth platformes which will be dedicated to NIR and VIS observations. A collaboration has recently been established among four Turkish universities including FMV Isik University (for adaptive optics systems), Middle East Technical University (fort measurement, test and calibration purposes), Istanbul University (for new technology instruments, e.g. MKIDs) and as the coordinator Ataturk University (for obtaining NIR and VIS instruments). In this paper the status of the recently approved FPI project and its aims are presented and possible collaboration opportunities are emphasized.

    Project management of DAG: Eastern Anatolia Observatory
    (SPIE, 2016) Keskin, Onur; Yeşilyaprak, Cahit; Yerli, Sinan Kaan; Zago, Lorenzo; Güver, Tolga; Aliş, Sinan
    The four meter DAG (Eastern Anatolia Observatory in Turkish) telescope is not only the largest telescope in Turkey but also the most promising telescope in the northern hemisphere with a large potential to offer scientific observations with its cutting edge technology. DAG is designed to be an AO telescope which will allow both infrared and visible observations with its two Nasmyth platforms dedicated to next generation focal plane instruments. In this paper, status updates from DAG telescope will be presented in terms of; (i) in house optical design of DAG, (ii) tender process of telescope, (iii) tender process of enclosure, and (iv) tender process of the observatory building. Also status updates from the focal plane instruments project and possible collaboration activities will be presented.

    Eastern Anatolia Observatory (DAG): Recent developments 2017
    (SPIE-INT Soc Optical Engineering, 2018-07-06) Yeşilyaprak, Cahit; Keskin, Onur
    East Anatolia Observatory (DAG) is the new observatory of Turkey with the optical (VIS) and near-infrared (NIR) largest telescope (4 m mirror) and its robust observing site infrastructure. This national project consists of three phases with DAG (telescope, enclosure, building, infrastructure), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant) and is supported by the Ministry of Development of Turkey. Almost all infrastructure (roads, geological and atmospheric surveys, electricity, fiber optics, water, generator, etc.) of DAG site (Erzurum/Turkey, 3170 m altitude) have been completed. The recent developments (telescope, enclosure, mirror, focal plane instruments, building, atmospheric studies, etc.) of DAG and its site in 2017 and 2018 were presented for the future possible collaborations for various astronomical instruments and telescopes which can be set up in DAG site.
