DAG telescope first light commissioning status (Invited Paper)

DAG, the 4 meter VIS/NIR telescope and the observatory, reached foreseen first light status at last: the enclosure acceptance is completed; to finalize the opto-mechanical alignment and pointing/tracking, the telescope mirrors have been exposed to heavens in absence of instrumentation. On the optical train; the two instruments that make the telescope distinctive, namely KORAY (the optical derotator) and flexible concept TROIA ( ExAO) system’s are characterized at the laboratory, and are anxiously waiting to be installed at their blessed location of mission – the diffraction limited Nasmyth platform along with the PLACID stellar coronagraph and DIRAC (NIR camera). We felt that PLACID, which is not yet lead star got jealous; so with the funding provided by the RACE-GO (ERC Project), within just after 60 days of it’s first mission, it will undergo for a technical makeover to a K-Band instrument. We now have a dilemma, the vacant seeing Nasmyth platform – the land lord- is still waiting for a cutting-edge tenant. Thus, the paper not only presents the telescope and it's instrumentation, but also reserves a dedicated section for possible co-operations/collaborations to take place on the
