... The real-time system for astronomical observations on the telescopes of the virtual observatory from ICAMER, SAO RAS, and BNO INR RAS . ... 81K Three large astronomical observatories-- ICAMER, SAO and BNO JNR RAS- are located in the compact area of the Northern Caucasus. ... The unification and synchronization of data-flows from these telescopes will allow one to carry out astronomical observations at a new level and to realize a virtual observatory with new capabilities for space research. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

A student observatory located on the roof of the Natural Science Building on Belknap Campus is used in the astronomy lab classes and by majors in the Department of Physics and Astronomy's B.S.
