FIRPO II was inaugurated at the russian SAO 6m telescope during a run in February 1997. At this time, FIRPO II is at SAO, pending approval of the next observing request and for an undefined period. More informations about logistic and observing procedures at that telescope can be found here.
This page contains specific informations relative to the instrument itself, such as its pre-amplifier, the list of available filters, the zero points. Note that some of this information and HTML pages may be under development or missing altogether, while I gather the necessary information. The news and messages, as well as the Standard Star magnitudes list, will be in common with those of FIRPO I. A lot of info on FIRPO II in connection with operations at SAO is available also on the luna/6m directory on the portable PC.

Status as of November 1997. In November, we have carried out a partially successful run, where it was possible to align the instrument, check the telescope pointing under the requirements of LO, and obtain SNR estimates. This and more is written in an internal memo. Here below you can see a few recent pictures. This is a *view of the Nasmyth 1 entrance beam, dichroic mirror, flange, support and instrument, TV camera tube. The following is a *view of the control table, with notebook (data acquisition), TV camera monitor, oscilloscope, offset/filter box, telescope control PC and monitor, intercom and microphone Finally, this is a *view of the cryostat attached to the vacuum pump in the main building at the SAO (Bukhovo) village.
