Instrumentation
 

The TJO is equipped with three instruments: two photometric imaging cameras (MEIA and MEIA2) and a medium-resolution spectrograph (ARES). Only MEIA2 is currently available to the community.  ARES is currently starting the commissioning phase at the observatory. MEIA has been decommissioned until further notice.

LAIA

The LAIA instrument is the optical imager of TJO, available from December 2018. It consists in two components: the CCD camera and the filter wheel. In addition, a system to acquire dome flats is available. Please, read the full information provided here when preparing observations for the TJO. Read more

ARES

ARES (Astronomical mid-REsolution Spectrograph) is a fiber-fed spectrograph, placed in a dedicated room at the observatory ground-flour. The main scientific programs that can be carried out with ARES involve the observation of relatively bright stars with a spectral resolution of λ/Δλ=12000 in two spectral windows (at 512 nm and 656 nm).

MEIA2 (decommissioned)

MEIA2 (Medium-format Efficient Imager for Astronomy 2) is the second-generation imaging instrument of the TJO telescope. It is composed by a high-efficiency CCD camera with a field of view of 12.3 arcmin and a set of Johnson-Cousins filters. A system for the acquisition of dome flat fields is also available. Read more

MEIA (decommissioned)

MEIA (Medium-format Efficient Imager for Astronomy) was the first-light instrument of the TJO telescope. It is composed by a high-efficiency CCD camera with a field of view of 12.3 arcmin and a set of Johnson-Cousins filters. A system for the acquisition of dome flat fields is also available. This instrument has been decommissioned until further notice. Read more
