One of the major observatories of the former Soviet Union grew up in the favorable
Armenian climate, in the village of Byurakan (situated north of the
capital, Yerevan, on the slopes of enormous Mount Aragats). The largest
instrument is the 2.6-meter telescope (not to be at all
confused with 2.6-m Shajn telescope in the Crimea of the
the 3-m Shane telescope half a word away in California).
The external access staircase enhances the unioque architectural style of its dome.
The best-known telescope at Byurakan is probably the 1-meter Schmidt telescope
used for the objective-prism survey begun by B.M. Markarian. The first
survey yielded
1500 objects, an
especially rich source of Seyfert galaxies
and starburst systems, selected for their relatively strong near-ultraviolet
flux. The second survey, continued after Markarian's death, has used
a higher dispersion to select emission-line objects at fainter levels,
revealing some especially interesting low-metallicity galaxies and
high-redshift QSOs. After the breakup of the USSR, the observatory
has struggled with funding and power problems.
The observatory has recently begun offering
viewing programs for the
tourist trade. Their publicity inexplicably refers to the "second largest
telescope in Europe", but since it's south of both the Greater and
Lesser Caucasus ranges, I really can only see Armenia as part of Asia.
These pictures were taken during IAU Symposium 121 on activity
in galaxies, held there in the summer of 1986.
