Eastern Anatolia Observatory (DAG): The status in 2020
East Anatolian Observatory's DAG telescope, with its 4m diameter primary mirror and VIS/IR observation capability, will be located on the Konakll-Karaya summit at an altitude of 3170 m, near the city of Erzurum, Turkey. ...
Advances for the 4m DAG Telescope in Flange derotator
The purpose of this study is expressing advances in design stages for in flange optical field derotator system for 4 meters DAG Telescope. In-Flange Derotator KORAY (K-mirror OpticalRelAY) is designed, analysed and ...
TROIA adaptive optics system for DAG Telescope
This paper presents the specifications of TROIA-TuRkish adaptive Optics system for Infrared Astronomy system, the science rationale for these specifications, and description of the site technical and environmental conditions ...
Optical design of the adaptive optics system for DAG, the new 4 m Turkish telescope
We present the design of the Adaptive Optics System for the new Turkish 4-m telescope (DAG). The AO will use a pyramid WFS, with a double prism and a no noise EM-CCD camera to allow for oversampling of the pupil images and ...
Coordination in building an observatory: A case study of Eastern Anatolian Observatory (DAG)
(SPIE-Int Soc Optical Engineering, 2018)
Eastern Anatolian Observatory (DAG) is designed to build on one of the summits of Palandoken Mountains in Erzurum, Turkey, at an altitude of 3,151 meters. The building is under construction since 2015 and expected to be ...

(SPIE-Int Soc Optical Engineering, 2018-06-06)
AMOS with EIE as a main subcontractor, was awarded a contract in November 2014 for the design, manufacturing and installation of a 4m-class telescope for the Turkish Eastern Anatolia Observatory (DAG) situated at 3170 m ...
Adaptive backstepping approach for 2-DOF telescopes despite unknown wind disturbance
(Institute of Electrical and Electronics Engineers Inc., 2019-07)
Small ground telescopes on the marked are widely used in many space observatories and scientific researches. There are three main problems in such telescopes; positioning of the focal point and the need of tuning for both ...
The flexible adaptive optics concept
(Instituto de Astrofisica de Canarias, 2017)
The availability of small deformable mirrors with large number of actuators and stroke, on one hand, and versatile wavefront sensors (pyramid WFS), on the other, allows the development of AO systems whose equivalent pitch ...
