Query: High-resolution spectrograph for telescopes of moderate diameter   A base model of the high-resolution fiber-fed spectrograph is developed. In
combination with the SAO 1-meter telescope the spectrograph has the following
parameters: spectral resolution R=45000, the number of simultaneous registered
orders is 86 within spectral region 3850$\div$10850 \AA{}, echelle orders are
overlapping for $\lambda <9000$ \AA{}.
