<p>If I am to apply at a telescope for viewing objects, how to determine (easily) what is the minimum and maximum possible RA and DEC visible from that telescope during that time of the year. For eg, take the telescope at paranal

You can see objects of all RAs - eg by looking at the relevant celestial pole. Similarly, whatever pole you can see is the maximum Dec (alternatively, subtract your latitude from 90 to get the 'maximum' Dec visible in the direction of the other pole.)
