Description
The INTEGRAL/EINSTEIN/ROSAT/NVSS objects IGR J17418-12122, 2E 1739.1-1210, 1RXS J174155.3-121157 and NVSS J174155-121201 have recently been suggested to be the same and considered to be a microquasar candidate with likely counterparts at optical and IR wavelengths (Tsarevsky et al. 2004, ATEL #239; Bassani et al. 2004, ATEL #232). In order to establish the identity of these sources, a 10-min spectrum of the tentative optical counterpart USNO 0778-0495204 was acquired on March 26.5 2004 (UT) with the FAST spectrograph attached to the 1.5-m telescope at the F. L. Whipple Observatory.

    HARMONI at ELT: HIPOTEC electronics and control system
    HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The

    GTCAO low-frequency tip-tilt offload to M2
    GTCAO is the instrument that implements Adaptive Optics on GTC. For atmospheric turbulence correction, GTCAO uses a deformable mirror. Unlike other AO systems, GTCAO does not include a dedicated mirror for low-frequency tip-tilt (TT) correction. In the absence of dedicated correction, the TT components of atmospheric turbulence are corrected by the
