Next: Instrumental data Up: Introduction Previous: Observatory data . Nearly every telescope seems to have some parts of the sky that are inaccessible. Trees, mountains, and even other telescopes obscure some areas above the horizon. ... In a surprising number of cases, the inaccessible regions extend into the parts of the sky one would normally use to measure extinction stars. Such restrictions should be placed in a separate ``obstruction'' table for each telescope. ...

... Since 2011 our observatory is a member of GLORIA (GLObal Robotic telescopes Intelligent Array for e-Science) project - wide international collaboration of 13 scientific institutions from 8 countries aiming at opening public access to robotic telescopes, as well as propagating astronomy in general. The GLORIA Project offers Internet users the possibility of studying the sky from professional observatories. ... The experiments are available at the users site of GLORIA. ... About GLORIA . ...
