DAG (Eastern Anatolia Observatory is read as "Dogu Anadolu Gozlemevi" in Turkish) is the newest and largest observatory of Turkey, constructed at an altitude of 3170 m in Konakli/Erzurum province, with an optical and near-infrared telescope (4 m in diameter) and its robust observing site infrastructure. This national project consists of three main phases: DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant). All these three phases are supported by the Ministry of Development of Turkey and funding is awarded to Ataturk University. Telescope, enclosure and building tenders were completed in 2014, 2015 and 2016, respectively. The final design of telescope, enclosure and building and almost all main infrastructure components of DAG site have been completed; mainly: road work, geological and atmospheric surveys, electric and fiber cabling, water line, generator system, cable car to summit. This poster explains recent developments of DAG project and talks about the future possible collaborations for various telescopes which can be constructed at the site.

DAG telescope site studies and infrastructure for possible international co-operations Yerli, Sinan Kaan; KESKİN, ONUR; Alis, Sinan (2016-07-01) The selected site for the 4 m DAG (Eastern Anatolian Observatory in Turkish) telescope is at "Karakaya Ridge", at 3170 m altitude (3150 m after summit management). The telescope's optical design is performed by the DAG technical team to allow infrared observation at high angular resolution, with its adaptive optics system to be built in Turkey. In this paper; a brief introduction about DAG telescope design; planned instrumentation; the meteorological data collected from 2008, clear night counts, short-term ...
EASTERN ANATOLIA OBSERVATORY (DAG): RECENT DEVELOPMENTS AND A PROSPECTIVE OBSERVING SITE FOR ROBOTIC TELESCOPES YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; KESKİN, ONUR (2015-10-02) This document (Eastern Anatolia Observatory (DAG) is the new observatory of Turkey with the optical and near-infrared largest telescope (4 m class) and its robust observing site infrastructure. This national project consists of three phases with DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant) and is supported by the Ministry of Development of Turkey. The tenders of telescope and enclosure have been made and almost al...
Observatory building design: a case study of DAG with infrastructure and facilities Sahmali, Ali Erkan; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; KESKİN, ONUR (2016-06-28) DAG (Eastern Anatolian Observatory in Turkish), will be built in one of the well-known mountain ridges of Erzurum, Turkey, at latitude of 39 degrees 46'50, longitude of 41 degrees 13'35 and an altitude of 3170 meters. As well as erecting the largest telescope of Turkey, the DAG project aims to establish an observatory complex both small in size and functional enough to give service to all astronomy community. In this paper, the challenge is explained in details: geological and geographical limitations, envi...
Project Management of DAG: Eastern Anatolia Observatory KESKİN, ONUR; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; Zago, Lorenzo; Guver, Tolga; Alis, Sinan (2016-06-28) 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 presen...
Agile development approach for the observatory control software of the DAG 4m telescope Gucsavd, B. Bulent; Coker, Deniz; YEŞİLYAPRAK, Cahit; KESKİN, ONUR; Zago, Lorenzo; Yerli, Sinan Kaan (2016-06-30) Observatory Control Software for the upcoming 4m infrared telescope of DAG (Eastern Anatolian Observatory in Turkish) is in the beginning of its lifecycle. After the process of elicitation-validation of the initial requirements, we have been focused on preparation of a rapid conceptual design not only to see the big picture of the system but also to clarify the further development methodology. The existing preliminary designs for both software (including TCS and active optics control system) and hardware sh...
