The Sky Maps
We have given two sets of all sky star maps. These maps can be used anywhere in India at about 21:00 hrs on the 15th of the given month. The same map can be used at ~22:00 hrs. earlier and at ~20:00 hrs. later that month.
The star map given here are drawn for central station of India (Long 82.5, Lat. +23deg 11′), at 21:00 hours Indian Standard Time (IST). The maps shows slightly more sky than that will be visible from this station. That is the angular diameter of the horizon circle is 220 deg. instead of normal 180deg.
The maps are drawn using stereographic projection (see wiki link), that preserves the shape but distorts the size. The constellations, therefore, close to the horizon comes out bigger than those close to the zenith.
Duo colour maps have star marked as black dots – larger the dot brighter is the star and text in red in colour. When you print these maps on a colour printer use with red touch light the text will nearly disappear but it will stand out in white or green light. You may, of course print these on a black and white printer.
