FFOREST
Fiber Feed Optical Russian Echelle Spectrograph
FFOREST is the fibre-feed high spectral resolution echelle spectrograph with a resolving power R=λ/Δλ from ∼30.000 to ∼100.000 covering broad wavelength range 4000 - 7500 Å. The portable fibre- optic input module is mounted in the prime focus of the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS). Presently, the instrument has two working fibre channels with equivalent widths of fibre cores of 0.7 and 1.4 arcsec. An additional calibration channel provides simultaneous observations of spectra from ThAr and Fabry–Perout (in development) calibration sources. The spectrograph is highly effective for detecting planets around stars with magnitudes as faint as 12m, thanks to the CCD camera developed by the Advanced Design Laboratory of SAO RAS. This CCD camera features an e2v 4k × 4k chip with 15 × 15 μm pixel size, and its electronics achieve a read-out noise of 2 - 3 electrons. Location Longitude: 41°26'30" Latitude: +43°39'12" Altitude: 2070 m Publications based on data obtained with the aid of FFOREST should quote the following reference paper: Valyavin et al. 2014, Astrophysical Bulletin, 69, 224
How to apply
Telescope time with 6-m telescope (and other telescopes) at Special Astrophysical Observatory is allocated twice a year. Applications for observing time must be submitted using the web-based interface accessible at the link given below. As a rule, applications for the first half of the following year are accepted from August 1 to September 10 of the current year and, from February 1 to March 10, applications for the second half of the year are accepted.
