The observational studies of high redshift universe seem dominated by large telescopes, <br />
but small telescopes (1-2 m class telescopes) are still making important contributions<br />
to understand the high redshift universe, out to z ~ 6. <br />
I will review our observational studies of high redshift universe using 1-2m class telescopes <br />
such as the KASI\/s Mt. Lemmon 1-m telescope, Bohyunsan Observatory\/s 1.8-m telescope,<br />
the Maidanak observatory\/s 1.5-m telescope, and the 68cm AKARI space telescope. <br />
The studies carried out with these telescopes cover various topics such as the gamma-ray <br />
burst afterglow, bright quasars, star-forming galaxies and AGNs, and high redshift quasars.<br />
Along with these findings, I will present exclusive photos of the passage to the Uzbekistan\/s <br />
Maidanak observatory.
